ZR431
ADJUSTABLE PRECISION ZENER SHUNT REGULATOR
Description Pin Assignments ADVANCE INFORMATION 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. (Top View) (Top View) VZ 1 VREF 3
