描述 Description

The UTC?TL432 is a three-terminal adjustable shunt regulator highly accurate 1.25V band gap reference with 0.5%, 1% tolerance. The device offers thermal stability, wide operating current (50mA) and an extended temperature range of 0° to 105°C for operation in power supply applications. The UTC TL432 offers a wide operating voltage range of up to 12V and is an excellent choice for voltage reference requirements in an isolated feedback circuit for 3.0V ~3.3V switching mode power supplies. The tight tolerance guaranteesa lower design cost for the power supply manufacturer by virtually eliminating the need for an extra power supply manufacturing process of the power supply.
