PRECISION MICROPOWER SHUNT VOLTAGE REFERENCES 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 60A 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.
