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.
