ZR431L
Adjustable precision shunt regulator
Summary
Description
The ZR431L is a three terminal adjustable shunt regulator offering excellent
temperature stability and output current handling capability up to 25mA.
The output voltage may be set to any chosen voltage between 1.24 and
10 volts by selection of two external divider resistors.
The devices can be used as a replacement for zener diodes in many
applications requiring an improvement in zener performance.
The ZR431L is particularly used in the feedback control loop of switch mode
power supplies. In this application the device 1.24 volt reference enables
the generation of low voltage supplies, typically 3.3 volts or 3 volts.
