ZENER SHUNT REGULATOR

ISSUE 4 – SEPTEMBER 2000

DEVICE DESCRIPTION

The ZR431 is a three terminal adjustable

shunt regulator offering excellent

temperature stability and output current

handling capability up to 100mA. The output

voltage may be set to any chosen voltage

between 2.5 and 20 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.
