Overview
LM4040 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 reversebreakdown voltages of 2.
048V, 2.
500V, 3.
000V, 3.
3V, 4.
096V, and 5.
000V.
Ideal for space-critical applications, the LM4040 is offered in the subminiature 3-pin SC70 surface-mount package (1.
8mm x 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, ensuring 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 wi...
