ZH431-Precision Adjustable Voltage Regulator Shunt Regulator
Device Description The ZH431 is a three-terminal adjustable shunt regulator providing excellent temperature stability and output current handling capability up to 30mA. The output voltage can be set to any selected voltage from 2.5 to 36 volts with two select external voltage divider resistors. The device can be used as a replacement for Zener diodes in many applications where Zener improvements are required in performance.They are also ideal for use in feedback circuits for off-line SMPUs, as well as for many general purpose voltage regulators and reference applications at low initial accuracy at low temperature Coefficients are the key requirement. ...
