Description

The ZR431L is a three terminal adjustable shunt regulator offering excel lent temperature stability and output current handling capability up to 25mA. The output voltage may be set to any chosen voltageetween 1.24 and 10 volts by selection of two external divider resistors.

The devices ZR431L 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.
