Low Voltage(1.24V) Adjustable Precision Shunt Regulator
PROGRAMMABLE PRECISION REFERENCES
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.
