ADJUSTABLE PRECISION

ZENER SHUNT REGULATOR

ISSUE 2 – FEBRUARY 1997

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.
