DESCRIPTION
The UTC TL432 is a three-terminal adjustable shunt regulator
SOP-8
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 ~

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.
