FEATURES

DESCRIPTION

Calogic’s CL432 is a 3-terminal Adjustable Shunt Regulator

highly accurate 1.25V bandgap reference with a 0.5%

tolerance. The device offers thermal stability, wide operating

current (100mA) and an extended temperature range of 0

105

offers a wide operating voltage range of up to 18V and is an

excellent choice for voltage reference requirements in an

isolated feedback circuit for 3.0V to 3.3V switching mode

power supplies.

The tight tolerance guarantees a lower

design cost for the power supply manufacturer by virtually

eliminating the need for an extra power supply manufacturing

process of the power supply.

The device is housed in several package options to meet the

designers criteria.
