MAXIM LM4041DEX3-1.2+T

The LM4041 shunt references use the bandgap principle to produce a stable, accurate voltage. The device behaves similarly to an ideal zener diode; a fixed voltage of +1.225V is maintained across its output terminals when biased with 60μA to 12mA of reverse current.

• 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×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 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.
