LM4041
LM4041 1.225V Precision micropower shunt voltage reference 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 surface mount packages which is ideal for applications where space saving is important. 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. The LM4041 is available to 0.5% C 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.
