LM4040
PRECISION MICROPOWER SHUNT VOLTAGE REFERENCES
Description
The LM4040 is a family of bandgap circuits designed to achieve
precision micro-power voltage references of 2.5V, 3.0V and 5.0V. The
devices are available in 0.2% B-grade, 0.5% C-grade and 1% D-
grade initial tolerances.
Pin Assignments
(Top View)
They are available in small outline SOT23 surface mount packages
which are ideal for applications where space is at a premium.
Excellent performance is maintained over the 60µA to 15mA
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 LM4040
voltage reference.
