LM4040

Precision micropower shunt voltage references

Description

The LM4040 is a family of bandgap circuits Excellent performance is maintained over the

designed to achieve precision micro-power 60µA to 15mA operating current range with a

voltage references of 2.5V, 3.0V and 5.0V. The typical temperature coefficient of only 20ppm/°C.

devices are available in 0.2% B-grade, 0.5% C- The device has been designed to be highly

grade and 1% D-grade initial tolerances.

tolerant of capacitive loads so maintaining

excellent stability.

They are available in small outline SOT23 and

SC75 surface mount package which are ideal This device offers a pin for pin compatible

for applications where space saving is alternative to the LM4040 voltage reference. The

important.

LM4040 is also available with AEC-Q100

approval; see LM4040Q datasheet
