General Description
The LM4040 is a precision two-terminal shunt mode,
bandgap voltage reference available in fixed reverse
breakdown voltages of 2.048V, 2.500V, 3.000V, 4.096V,
and 5.000V. Ideal for space-critical applications, the
LM4040 is offered in the subminiature 3-pin SC70 sur-
face-mount package (1.8mm ✕1.8mm), 50% smaller
than comparable devices in SOT23 surface-mount
packages (SOT23 versions are also available).
Laser-trimmed resistors ensure precise initial accuracy.
With a 100ppm/°C temperature coefficient, the device
is offered in four grades of initial accuracy ranging from
0.1% to 1%. The LM4040 has a 60µA to 15mA shunt
current capability with low dynamic impedance, ensur-
ing stable reverse breakdown voltage accuracy over a
wide range of operating temperatures and currents.
The LM4040 does not require an external stabilizing
capacitor while ensuring stability with any capacitive
load.
For a 1.225V output version, refer to the LM4041 data
sheet.

Note 1: All devices are 100% production tested at +25°C and are guaranteed by design for TA= TMIN to TMAX, as specified.
Note 2: The overtemperature limit for Reverse Breakdown Voltage Tolerance is defined as the room-temperature Reverse
Breakdown Voltage Tolerance ±[(∆VR/ ∆T)(max∆T)(VR)], where ∆VR/ ∆T is the VRtemperature coefficient, max∆T is the
maximum difference in temperature from the reference point of +25°C to TMIN or TMAX, and VRis the reverse breakdown
voltage. The total overtemperature tolerance for the different grades in the temperature range where max∆T = +65°C is
shown below:
A grade: ±0.75% = ±0.1% ±100 ppm/°C ✕65°C
B grade: ±0.85% = ±0.2% ±100 ppm/°C ✕65°C
C grade: ±1.15% = ±0.5% ±100 ppm/°C ✕65°C

Detailed Description
The LM4040 shunt references use the bandgap princi-
ple to produce a stable, accurate voltage. The device
behaves similarly to an ideal zener diode; a fixed volt-
age is maintained across its output terminals when
biased with 60µA to 15mA of reverse current. The
LM4040 behaves similarly to a silicon diode when
biased with forward currents up 10mA.
Figure 3 shows a typical operating circuit. The LM4040
is ideal for providing a stable reference from a high-
voltage power supply.
Applications Information
The LM4040’s internal pass transistor is used to main-
tain a constant output voltage (VSHUNT) by sinking the
necessary amount of current across a source resistor.
The source resistance (RS) is determined from the load
current (ILOAD) range, supply voltage (VS) variations,
VSHUNT, and desired quiescent current.
Choose the value of RSwhen VSis at a minimum and
ILOAD is at a maximum. Maintain a minimum ISHUNT of
60µA at all times. The RSvalue should be large enough
to keep ISHUNT less than 15mA for proper regulation
when VSis maximum and ILOAD is at a minimum. To
prevent damage to the device, ISHUNT should never
exceed 20mA.
Therefore, the value of RSis bounded by the following
equation:
[VS(MIN) - VR] / [60µA + ILOAD(MAX)] > RS>
[VS(MAX) - VR] / [20mA + ILOAD(MIN)]
Choosing a larger resistance minimizes the total power
dissipation in the circuit by reducing the shunt current
(PD(TOTAL) = VS✕ISHUNT). Provide a safety margin to
incorporate the worst-case tolerance of the resistor
used. Ensure that the resistor’s power rating is ade-
quate, using the following general power equation:
PDR= ISHUNT ✕(VS(MAX) - VSHUNT)
Output Capacitance
The LM4040 does not require an external capacitor for
frequency stability and is stable for any output capaci-
tance.
Temperature Performance
The LM4040 typically exhibits an output voltage tem-
perature coefficient within ±15ppm/°C. The polarity of
the temperature coefficient may be different from one
device to another; some may have positive coefficients,
and others may have negative coefficients.
