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.

The deviation parameters ΔVREF/ΔT and ΔIREF/ΔT are defined as the differences between the maximum and
minimum values obtained over the recommended temperature range. The average full-range temperature
coefficient of the reference voltage, αVREF, is defined as :

Where :
ΔTA is the recommended operating free-air temperature range of the device.
