ZR2431-Precision Adjustable Voltage Regulator Shunt Regulator
Device Description The ZR2431 is a three-terminal adjustable shunt regulator providing excellent temperature stability and output current handling capability up to 25mA. The output voltage can be set to any selected voltage between 1.24 and 15 volts by two external resistor dividers. This device can be used as a replacement for Zener diodes in many applications where improvements in Zener performance are required. Especially the feedback control loop supply of switching power supply is used in ZR2431. In this application the 1.24 reference voltage can be lower than the power supply voltage, usually 3.3 volts or 3 volts.
