ZR431
Adjustable precision shunt regulator
Description
The ZR431 is a three terminal adjustable
shunt
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.
