0.8V PRECISION ADJUSTABLE

SHUNT REFERENCE

REGULATORS

DESCRIPTION

The UTC TL432D is a three-terminal adjustable shunt

regulator highly accurate 0.8V band gap 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 TL432D

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 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.

FEATURES

* Temperature-Compensated: 50ppm/

°C

* Internal Amplifier with 50mA Capability

* Nominal Temperature Range Extended to 105

°C

* Low Frequency Dynamic Output Impedance:<150mΩ

* Low Output Noise

* Halogen Free
