3 Description

The LM337L is an adjustable 3-pin negative voltage

regulator capable of supplying 100 mA over a –1.2-V

to –37-V output range. The LM337L is easy to use

and requires only two external resistors to set the

output voltage. Both line and load regulation are

better than standard fixed regulators. The LM337L is

packaged in a standard, easy-to-use TO-92 transistor

package.

In addition to higher performance than fixed

regulators, the LM337L offers full overload protection.

Included on the chip are current limit, thermal

overload protection, and safe area protection. All

overload protection circuitry remains fully functional

even if the adjustment pin is disconnected.

Normally, only a single 1-µF solid tantalum output

capacitor is required unless the device is situated

more than 6 inches from the input filter capacitors, in

which case an input bypass is required. A larger

output capacitor can be added to improve transient

response. The adjustment pin can be bypassed to

achieve very high ripple rejection ratios, which are

difficult to achieve with standard 3-pin regulators.

Besides replacing fixed regulators, the LM337L is

useful in a wide variety of other applications. Because

the regulator is floating and monitors only the input-

to-output differential voltage, supplies of several

hundred volts can be regulated as long as the

maximum input-to-output differential is not exceeded.

The LM337L makes a simple adjustable switching

regulator, a programmable output regulator, or by

connecting a fixed resistor between the adjustment

and output, the LM337L can be used as a precision

current regulator. Supplies with electronic shutdown

can be achieved by clamping the adjustment pin to

ground, which programs the output to 1.2 V, where

most loads draw little current.

The LM337L is available in a standard TO-92

transistor package and a standard SO-8 surface

mount package. The LM337L is rated for operation

over a –25°C to 125°C range.

For applications requiring output current in excess of

0.5 A and 1.5 A, The LM137 series may be suitable.

For the positive complement, the LM117 and LM317L

series are options.

7 Detailed Description

7.1 Overview

The LM337L devices are adjustable 3-terminal negative-voltage regulators capable of supplying 100 mA over an

output voltage range of –1.2 V to –37 V. They are exceptionally easy to use, requiring only two external resistors

to set the output voltage and one output capacitor for frequency compensation. In addition, LM337L offers full

overload protection. Included on the chip are current limit, thermal overload protection and safe area protection.

All overload protection circuitry remains fully functional even if the adjustment terminal is disconnected. The

LMx37 devices serve a wide variety of applications, including local on-card regulation, programmable output-

voltage regulation, and precision current regulation.

7.2 Functional Block Diagram

7.3 Feature Description

7.3.1 Output Voltage Adjustment

The Adjustment (ADJ) pin serves as a voltage adjustment reference for the output. The ADJ pin can be attached

to a resistor divider circuit to adjust the output voltage level. The reference voltage VADJ will typically be 1.25 V

higher than VO.

7.4 Device Functional Modes

7.4.1 Protection Diodes

When external capacitors are used with any IC regulator, it is sometimes necessary to add protection diodes to

prevent the capacitors from discharging through low current points into the regulator. Most 10-μF capacitors have

low enough internal series resistance to deliver 20-A spikes when shorted. Although the surge is short, there is

enough energy to damage parts of the IC. When an output capacitor is connected to a negative output regulator

and the input is shorted, the output capacitor pulls current out of the output of the regulator. The current depends

on the value of the capacitor, the output voltage of the regulator, and the rate at which VIN is shorted to ground.

The bypass capacitor on the adjustment terminal can discharge through a low current junction. Discharge occurs

when either the input, or the output, is shorted. Figure 15 shows the placement of the protection diodes.

Device Functional Modes (continued)

When CL is larger than 20 μF, D1 protects the LM337L in case the input supply is shorted.

When C2 is larger than 10 μF and −VOUT is larger than −25V, D2 protects the LM337L in case the output is shorted.

8 Application and Implementation

NOTE

Information in the following applications sections is not part of the TI component

specification, and TI does not warrant its accuracy or completeness. TI’s customers are

responsible for determining suitability of components for their purposes. Customers should

validate and test their design implementation to confirm system functionality.

8.1 Application Information

The LM337L is a negative output linear regulator with high accuracy and a wide temperature range. An output

capacitor can be added to further improve transient response, and the ADJ pin can be bypassed to achieve very

high ripple-rejection ratios. The device's functionality can be utilized in many different applications that require

negative voltage supplies, such as bipolar amplifiers, operational amplifiers, and constant current regulators.

8.2 Typical Applications

8.2.1 1.2-V to 25-V Adjustable Regulator

Full output current not available at high input-output voltages

†C1 = 1-μF solid tantalum or 10-μF aluminum electrolytic required for stability

*C2 = 1-μF solid tantalum is required only if regulator is more than 4″from power supply filter capacitor

Figure 6. 1.2-V to 25-V Adjustable Regulator Diagram

8.2.1.1 Design Requirements

The device component count is very minimal, employing two resistors as part of a voltage divider circuit and an

output capacitor for load regulation. An input capacitor is needed if the device is more than 4 in. from the filter

capacitors.

8.2.1.2 Detailed Design Procedure

The output voltage is set based on the selection of the two resistors (R1 and R2) as shown in Equation 1.

8.2.2 Regulator With Trimmable Output Voltage

Figure 8. Regulator with Trimmable Output Voltage Diagram

8.2.2.1 Design Requirements

This design uses five resistors with two being used for a voltage divider circuit and the other three used for

trimming the output voltage. The benefit is lower cost as compared to using a trim pot. An output capacitor is

needed to improve load regulation.

8.2.2.2 Detailed Design Procedure

This design will trim the output voltage to within 1% of –22 V. The parallel combination of R1, R3, R4 and R5

serve as the bottom resistance and R2 as the top resistance in the voltage divider that sets the output voltage.

Trim Procedure:

• If VOUT is –23.08 V or larger, do not use R3, otherwise leave it in.

• Then if VOUT is –22.47 V or bigger, do not use R4, otherwise leave it in.

• Then if VOUT is –22.16 V or bigger, do not use R5, otherwise leave it in.

This will trim the output to well within 1% of –22 VDC, without any of the expense or trouble of a trim pot (see LB-

46). This technique can be used at any output voltage level.

9 Power Supply Recommendations

The input supply to the LM337L must be kept at a voltage level such that its maximum input to output differential

voltage rating is not exceeded. The minimum dropout voltage must also be met with extra headroom when

possible to keep the LM337L in regulation. TI recommends an input capacitor, especially when the input pin is

placed more than 4 in. away from the power-supply filter capacitor.

10 Layout

10.1 Layout Guidelines

Some layout guidelines must be followed to ensure proper regulation of the output voltage with minimum noise.

Traces carrying the load current must be wide to reduce the amount of parasitic trace inductance and the

feedback loop from VOUT to ADJ must be kept as short as possible. To improve PSRR, a bypass capacitor can

be placed at the ADJ pin and must be placed as close as possible to the IC. In cases when VIN shorts to ground,

an external diode must be placed from VIN to VOUT to divert the surge current into the output capacitor and

protect the IC. Similarly, in cases when a large bypass capacitor is placed at the ADJ pin and VOUT shorts to

ground, an external diode must be placed from VOUT to ADJ to provide a path for the bypass capacitor to

discharge. These diodes must be placed close to the corresponding IC pins to increase their effectiveness.

IMPORTANT NOTICE

Texas Instruments Incorporated (TI) reserves the right to make corrections, enhancements, improvements and other changes to its

semiconductor products and services per JESD46, latest issue, and to discontinue any product or service per JESD48, latest issue. Buyers

should obtain the latest relevant information before placing orders and should verify that such information is current and complete.

TI’s published terms of sale for semiconductor products (http://www.ti.com/sc/docs/stdterms.htm) apply to the sale of packaged integrated

circuit products that TI has qualified and released to market. Additional terms may apply to the use or sale of other types of TI products and

services.

Reproduction of significant portions of TI information in TI data sheets is permissible only if reproduction is without alteration and is

accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such reproduced

documentation. Information of third parties may be subject to additional restrictions. Resale of TI products or services with statements

different from or beyond the parameters stated by TI for that product or service voids all express and any implied warranties for the

associated TI product or service and is an unfair and deceptive business practice. TI is not responsible or liable for any such statements.

Buyers and others who are developing systems that incorporate TI products (collectively, “Designers”) understand and agree that Designers

remain responsible for using their independent analysis, evaluation and judgment in designing their applications and that Designers have

full and exclusive responsibility to assure the safety of Designers' applications and compliance of their applications (and of all TI products

used in or for Designers’ applications) with all applicable regulations, laws and other applicable requirements. Designer represents that, with

respect to their applications, Designer has all the necessary expertise to create and implement safeguards that (1) anticipate dangerous

consequences of failures, (2) monitor failures and their consequences, and (3) lessen the likelihood of failures that might cause harm and

take appropriate actions. Designer agrees that prior to using or distributing any applications that include TI products, Designer will

thoroughly test such applications and the functionality of such TI products as used in such applications.

TI’s provision of technical, application or other design advice, quality characterization, reliability data or other services or information,

including, but not limited to, reference designs and materials relating to evaluation modules, (collectively, “TI Resources”) are intended to

assist designers who are developing applications that incorporate TI products; by downloading, accessing or using TI Resources in any

way, Designer (individually or, if Designer is acting on behalf of a company, Designer’s company) agrees to use any particular TI Resource

solely for this purpose and subject to the terms of this Notice.

TI’s provision of TI Resources does not expand or otherwise alter TI’s applicable published warranties or warranty disclaimers for TI

products, and no additional obligations or liabilities arise from TI providing such TI Resources. TI reserves the right to make corrections,

enhancements, improvements and other changes to its TI Resources. TI has not conducted any testing other than that specifically

described in the published documentation for a particular TI Resource.

Designer is authorized to use, copy and modify any individual TI Resource only in connection with the development of applications that

include the TI product(s) identified in such TI Resource. NO OTHER LICENSE, EXPRESS OR IMPLIED, BY ESTOPPEL OR OTHERWISE

TO ANY OTHER TI INTELLECTUAL PROPERTY RIGHT, AND NO LICENSE TO ANY TECHNOLOGY OR INTELLECTUAL PROPERTY

RIGHT OF TI OR ANY THIRD PARTY IS GRANTED HEREIN, including but not limited to any patent right, copyright, mask work right, or

other intellectual property right relating to any combination, machine, or process in which TI products or services are used. Information

regarding or referencing third-party products or services does not constitute a license to use such products or services, or a warranty or

endorsement thereof. Use of TI Resources may require a license from a third party under the patents or other intellectual property of the

third party, or a license from TI under the patents or other intellectual property of TI.

TI RESOURCES ARE PROVIDED “AS IS” AND WITH ALL FAULTS. TI DISCLAIMS ALL OTHER WARRANTIES OR

REPRESENTATIONS, EXPRESS OR IMPLIED, REGARDING RESOURCES OR USE THEREOF, INCLUDING BUT NOT LIMITED TO

ACCURACY OR COMPLETENESS, TITLE, ANY EPIDEMIC FAILURE WARRANTY AND ANY IMPLIED WARRANTIES OF

MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT OF ANY THIRD PARTY INTELLECTUAL

PROPERTY RIGHTS. TI SHALL NOT BE LIABLE FOR AND SHALL NOT DEFEND OR INDEMNIFY DESIGNER AGAINST ANY CLAIM,

INCLUDING BUT NOT LIMITED TO ANY INFRINGEMENT CLAIM THAT RELATES TO OR IS BASED ON ANY COMBINATION OF

PRODUCTS EVEN IF DESCRIBED IN TI RESOURCES OR OTHERWISE. IN NO EVENT SHALL TI BE LIABLE FOR ANY ACTUAL,

DIRECT, SPECIAL, COLLATERAL, INDIRECT, PUNITIVE, INCIDENTAL, CONSEQUENTIAL OR EXEMPLARY DAMAGES IN

CONNECTION WITH OR ARISING OUT OF TI RESOURCES OR USE THEREOF, AND REGARDLESS OF WHETHER TI HAS BEEN

ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

Unless TI has explicitly designated an individual product as meeting the requirements of a particular industry standard (e.g., ISO/TS 16949

and ISO 26262), TI is not responsible for any failure to meet such industry standard requirements.

Where TI specifically promotes products as facilitating functional safety or as compliant with industry functional safety standards, such

products are intended to help enable customers to design and create their own applications that meet applicable functional safety standards

and requirements. Using products in an application does not by itself establish any safety features in the application. Designers must

ensure compliance with safety-related requirements and standards applicable to their applications. Designer may not use any TI products in

life-critical medical equipment unless authorized officers of the parties have executed a special contract specifically governing such use.

Life-critical medical equipment is medical equipment where failure of such equipment would cause serious bodily injury or death (e.g., life

support, pacemakers, defibrillators, heart pumps, neurostimulators, and implantables). Such equipment includes, without limitation, all

medical devices identified by the U.S. Food and Drug Administration as Class III devices and equivalent classifications outside the U.S.

TI may expressly designate certain products as completing a particular qualification (e.g., Q100, Military Grade, or Enhanced Product).

Designers agree that it has the necessary expertise to select the product with the appropriate qualification designation for their applications

and that proper product selection is at Designers’ own risk. Designers are solely responsible for compliance with all legal and regulatory

requirements in connection with such selection.

Designer will fully indemnify TI and its representatives against any damages, costs, losses, and/or liabilities arising out of Designer’s non-

compliance with the terms and provisions of this Notice.
