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.
They are available in small outline SOT23 and
SC75 surface mount package which are ideal
for applications where space saving is
important.

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. The
LM4040 is also available with AEC-Q100
approval; see LM4040Q datasheet
