ADJUSTABLE PRECISION
ZENER SHUNT REGULATOR
ISSUE 4 – SEPTEMBER 2000
DEVICE DESCRIPTION
The ZR431 is a three terminal adjustable
shunt regulator offering excellent
temperature stability and output current
handling capability up to 100mA. 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.
