Hot-selling and scarce ZR431LF02TA ADJUSTABLE PRECISION SHUNT REGULATOR SOT23 spot stock

Product Descriptions

The ZR431L is a three terminal adjustable shunt regulator offering excellent temperature stability and output current handling capability up to 25mA. The output voltage may be set to any chosen voltage between  1.24  and  10  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.

The  ZR431L  is  particularly  used  in  the  feedback  control  loop  of switch mode power supplies. In this application the device 1.24 volt reference enables the generation of low voltage supplies, typically3.3 volts or 3 volts.
