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.
