1.25V PRECISION

ADJUSTABLE SHUNT

REFERENCE REGULATORS

DESCRIPTION

The UTC TL432 is a three-terminal adjustable shunt regulator

highly accurate 1.25V bandgap reference with 1%, 2% 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

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.

FEATURES

*Temperature-Compensated:50ppm/

°C

*Internal amplifier with 50mA capability

*Nominal temperature range extended to 105

°C
