(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings
only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended
Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/ Distributors for availability and
specifications.
(3) The maximum power dissipation must be derated at elevated temperatures and is dictated by TJmax (maximum junction temperature),
RθJA (junction to ambient thermal resistance), and TA(ambient temperature). The maximum allowable power dissipation at any
temperature is PDmax = (TJmax −TA)/RθJA or the number given in the Absolute Maximum Ratings, whichever is lower. For the LM4050-N,
TJmax = 150°C, and the typical thermal resistance (RθJA), when board mounted, is 326°C/W for the SOT-23 package.
(4) High junction temperatures degrade operating lifetimes. Operating lifetime is de-rated for junction temperatures greater than 125°C.

(1) Limits are 100% production tested at 25°C. Limits over temperature are guaranteed through correlation using Statistical Quality Control
(SQC) methods. The limits are used to calculate National's AOQL.
(2) Typicals are at TJ= 25°C and represent most likely parametric norm.
(3) The overtemperature limit for Reverse Breakdown Voltage Tolerance is defined as the room temperature Reverse Breakdown Voltage
Tolerance ±[(ΔVR/ΔT)(maxΔT)(VR)]. Where, ΔVR/ΔT is the VRtemperature coefficient, maxΔT is the maximum difference in temperature
from the reference point of 25°C to T MIN or TMAX, and VRis the reverse breakdown voltage. The total overtemperature tolerance for the
different grades in the industrial temperature range where maxΔT = 65°C is shown below: A-grade: ±0.425% = ±0.1% ±50 ppm/°C ×
65°C B-grade: ±0.525% = ±0.2% ±50 ppm/°C × 65°C C-grade: ±0.825% = ±0.5% ±50 ppm/°C × 65°C. Therefore, as an
example, the A-grade LM4050-N-2.5 has an overtemperature Reverse Breakdown Voltage tolerance of ±2.5V × 0.425% = ±11 mV.
(4) Load regulation is measured on pulse basis from no load to the specified load current. Output changes due to die temperature change
must be taken into account separately.
(5) Thermal hysteresis is defined as the difference in voltage measured at 25°C after cycling to temperature –40°C and the 25°C
measurement after cycling to temperature 125°C.

8 Detailed Description
8.1 Overview
The LM4050-N device is a precision micropower shunt voltage reference. The part comes in 6 different fixed-
output voltage options for space-constrained applications, removing the need for feedback resistors. The voltage
tolerance accuracies are ±0.1%, ±0.2%, and ±0.5% for Versions A, B, and C, respectively. The LM4050-N comes
in two application versions, Industrial and Extended temperature range, which are operational from –40°C to
85°C and –40°C to 125°C, respectively.
8.2 Functional Block Diagram
8.3 Feature Description
The LM4050-N behaves as a high-precision Zener diode. The voltage is regulated between its cathode and
anode which is dependent on the current being supplied to the cathode. This current is needed for the LM4050-N
to regulate within the specified limits. Refer to the minimum and maximum operating requirements for the specific
voltage option used. The LM4050-N is internally compensated to be stable without the use of an output
capacitor. However, if desired, a bypass capacitor may be used.
8.4 Device Functional Modes
The LM4050-N can only operate in closed loop due to the fact that the feedback resistors are internal to the
device. Additionally, the output voltage cannot be adjusted for the same reason. The output voltage is regulated
in a closed loop, provided the Rs (see Functional Block Diagram) resistor is sized to deliver the current to the
cathode within the limits specified for the fixed-voltage version being used.

9 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.
9.1 Application Information
The LM4050-N is a precision micropower curvature-corrected bandgap shunt voltage reference. For space
critical applications, the LM4050-N is available in the sub-miniature SOT-23 surface-mount package. The
LM4050-N has been designed for stable operation without the need of an external capacitor connected between
the + pin and the −pin. If, however, a bypass capacitor is used, the LM4050-N remains stable. Reducing design
effort is the availability of several fixed reverse breakdown voltages: 2.048 V, 2.5 V, 4.096 V, 5 V, 8.192 V, and
10 V. The minimum operating current increases from 60 μA for the LM4050-N-2.0 to 100 μA for the LM4050-N-
10.0. All versions have a maximum operating current of 15 mA.
LM4050-Ns in the SOT-23 packages have a parasitic Schottky diode between pin 2 (−) and pin 3 (Die attach
interface contact). Therefore, pin 3 of the SOT-23 package must be left floating or connected to pin 2.
The 4.096-V version allows single 5-V 12-bit ADCs or DACs to operate with an LSB equal to 1 mV. For 12-bit
ADCs or DACs that operate on supplies of 10 V or greater, the 8.192-V version gives 2 mV per LSB.
The typical thermal hysteresis specification is defined as the change in 25°C voltage measured after thermal
cycling. The device is thermal cycled to temperature –40°C and then measured at 25°C. Next the device is
thermal cycled to temperature 125°C and again measured at 25°C. The resulting VOUT delta shift between the
25°C measurements is thermal hysteresis. Thermal hysteresis is common in precision references and is induced
by thermal-mechanical package stress. Changes in environmental storage temperature, operating temperature
and board mounting temperature are all factors that can contribute to thermal hysteresis.
In a conventional shunt regulator application (Figure 10) , an external series resistor (RS) is connected between
the supply voltage and the LM4050-N. RSdetermines the current that flows through the load (IL) and the
LM4050-N (IQ). Since load current and supply voltage may vary, RSshould be small enough to supply at least
the maximum guaranteed IRMIN (spec. table) to the LM4050-N even when the supply voltage is at its minimum
and the load current is at its maximum value. When the supply voltage is at its maximum and ILis at its
minimum, RSshould be large enough so that the current flowing through the LM4050-N is less than 15 mA.
RSis determined by the supply voltage, (VS), the load and operating current, (ILand IQ), and the LM4050-N's
reverse breakdown voltage, VR.

10 Power Supply Recommendations
Noise on the power supply input to RScan affect output noise performance. Noise performance can be reduced
by using an optional bypass capacitor at the input side of RSand Ground. TI recommends a 0.1-µF ceramic
capacitor or higher.
11 Layout
11.1 Layout Guidelines
Place RSas close to the cathode as possible. If an input and output capacitor is used, place this as close to the
reference as possible.

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.
