ZHT431
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.
