Datasheet
GENERAL DESCRIPTION
The CM431L is a low voltage three terminal adjustable shunt
regulator with thermal stability guaranteed over temperature.
The output voltage can be adjusted to any value from 1.24V
(V
typical dynamic output impedance of 0.25Ω. Active output
circuitry provides a very sharp turn on characteristic, making
the CM431L an excellent replacement for zener diodes.
The CM431L shunt regulator is available in four voltage
tolerances(0.5%, 0.7%, 1.0% and 2.0%)and four package
options (SOT-23-3, SOT-23-5, SOT-89, TO-92, and SOP-8).
Four voltage tolerances allow the designer the opportunity to
select the proper cost/tolerance for their application.
