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 0o to 105oC for operation in power supply applications. The CL432 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.
