The TL432A is a three-terminal Shunt Voltage Reference

providing a highly accurace 1.24 V, 1.25V bandgap reference

with 1.0 % tolerance.

The TL432A thermal stability and wide operating current

(100mA), makes is suitable for all variety of applications that

are looking for a low cost solution with high performance.

The TL432A is an ideal voltage reference in an isolated feed

circuit for 3.0V to 3.3V switching mode power supplies.
