ZHT431C01STOB

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.
