Improved Precision Micropower Shunt Voltage
Reference with Multiple Reverse Breakdown Voltages
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, 3.3V,
4.096V, and 5.000V. Ideal for space-critical applica-
tions, the LM4040 is offered in the subminiature 3-pin
SC70 surface-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.
The LM4040 is guaranteed over the temperature range
of -40°C to +125°C.
For a 1.225V output version, refer to the LM4041 data
sheet.
