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.
