FEATURES
APPLICATION
DESCRIPSION
The TL432 is a three-terminal Shunt Voltage Reference
providing a highly accuracy 1.24V band-gap reference
with 0.5% and 1.0% tolerance. The TL432 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 TL432 is an
ideal voltage reference in an isolated feed circuit for 3.0V
to 3.3V switching mode power supplies.
