Hot-selling and scarce LM4040BIM3-4.1 Precision Micropower Shunt Voltage Reference SOT23-3 spot stock
LM4040BIM3-4.1 Precision Micropower Shunt Voltage Reference SOT23-3 spot stock
Product Descriptions
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 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, 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 with any capacitive load.
For a 1.225V output version, refer to the LM4041 data sheet.
