The LM4041 is a precision two-terminal shunt mode, bandgap voltage reference with a fixed reverse breakdown voltage of 1.225V. Ideal for space-critical applications, the LM4041 is offered in the subminiature 3-pin SC70 surface-mount package (1.8mm x 1.8mm), 50% smaller than comparable devices in SOT23 surfacemount 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 LM4041 has a 60µA to 12mA shunt current capability with low dynamic impedance, ensuring stable reverse-breakdown voltage accuracy over a wide range of operating temperatures and currents.
The LM4041 does not require an external stabilizing capacitor while ensuring stability with any capacitive load.
The LM4041 is guaranteed over the temperature range -40°C to +125°C.
