DESCRIPTION  
The UTC TL432 is a three-terminal adjustable shunt regulator  
3

highly accurate 1.25V band gap reference with 0.5%, 1% tolerance.  
The device offers thermal stability, wide operating current (50mA)  
and an extended temperature range of 0to 85C 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 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.
