| UNISONIC TECHNOLOGIES CO., LTD TL432C 1.24V PRECISION ADJUSTABLE SHUNT REFERENCE REGULATORS DESCRIPTION The UTC TL432C is a three-terminal adjustable shunt regulator highly accurate 1.24V bandgap reference with 1%, 2% tolerance. The device offers thermal stability, wide operating current (50mA) and an extended temperature range of 0 to 105C for operation in power supply applications. The UTC TL432C 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 quarantees 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.
