LM4040
Precision micropower shunt voltage references
www.DataSheet4U.com
Description
The LM4040 is a family of bandgap circuits
designed to achieve precision micro-power
voltage references of 2.5V and 5.0V. The
devices are available in 0.5% C-grade and 1%
D-grade initial tolerances.
They are available in small outline SOT23
surface mount package which is ideal for
applications where space saving is important.
Features
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.
Applications
