DESCRIPTION
Calogic’s CL432B is a 3-terminal Adjustable Shunt Regulator
highly accurate 1.25V bandgap reference with a 2%
tolerance. The device offers thermal stability, wide operating
current (100mA) and an extended temperature range of 0o to
105oC for operation in power supply applications. The CL432B
offers a wide operating voltage range of up to 10V 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.
