DEVICE 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.
