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 and 5.0V. The typical temperature coefficient of only 20ppm/°C.

devices are available in 0.5% C-grade and 1% The device has been designed to be highly

D-grade initial tolerances.

tolerant of capacitive loads so maintaining

excellent stability.

They are available in small outline SOT23

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

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