ADJUSTABLE PRECISION ZENER SHUNT REGULATOR

Description

The ZHT431 is a three terminal adjustable shunt regulator

offering excellent temperature stability and output current

handling capability up to 100mA. The device offers

extended operating temperature range working from -55 to

+125°C.

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.
