1 / 7 page LM4041 PRECISION MICROPOWER SHUNT VOLTAGE REFERENCES LM4041 Document number: DS32020 Rev. 8 - 2 1 of 7 www.diodes.com September 2011 © Diodes Incorporated Description The LM4041 is a bandgap circuit designed to achieve a precision micro-power voltage reference of 1.225 V. The device is available in the small outline SOT23 and SC70-5 surface mount packages which are ideal for applications where space saving is important. Both packages are available to 0.5% C grade and 1% D grade for precision applications. Excellent performance is maintained over the 60µA to 12mA operating current range with a typical temperature coefficient of only 20ppm/°C. The device has been designed to be highly tolerant of capacitive loads so maintaining excellent stability. This device offers a pin for pin compatible alternative to the LM4041 voltage reference in both adjustable and 1.225V output variants. Features • Small packages: SOT23, SC70-5 • No output capacitor required • Output voltage tolerance • LM4041C: ±0.5% at 25°C • LM4041D: ±1% at 25°C • Low output noise: 20µVrms (10Hz to 10kHz) • Wide operating current range: 60µA to 12mA • Extended temperature range: -40°C to +125°C • Low temperature coefficient : 100ppm/°C (max) • All parts AEC-Q100 Grade1 qualified Applications • Battery powered equipment • Precision power supplies • Portable instrumentation • Portable communications devices • Notebook and palmtop computers • Data acquisition systems Pin Assignments LM4041_F (SOT23) Pin 3 must left floating or connected to pin 2.
