The ZR431LC01STOB is a three terminal adjustable shunt regulator offering excellenttemperature stability and output current handling capability up to 25mA.The output voltage may be set to any chosen voltage between 1.24 and10 volts by selection of two external divider resistors.The devices can be used as a replacement for zener diodes in manyapplications requiring an improvement in zener performance.The ZR431LC01STOB is particularly used in the feedback control loop of switch modepower supplies. In this application the device 1.24 volt reference enablesthe generation of low voltage supplies, typically 3.3 volts or 3 volts.
