DEVICE DESCRIPTION
The ZHT2431 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 15 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 ZHT2431 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, typically 3.3 volts or 3 volts.
The ZHT2431 is intended for use over the
extended operating range of -55°C to 125°C.
