UTC TL432
LINEAR INTEGRATED CIRCUIT

1.25V PRECISION ADJUSTABLE SHUNT REFERENCE / AMPLIFIER
DESCRIPTION
The UTC TL432 is a three-terminal adjustable shunt regulator highly accurate 1.25V bandgap reference with a 0.5% 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 to 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.
