Data Sheet
ADJUSTABLE PRECISION SHUNT REGULATORS
General Description
The AN431 series ICs are three-terminal adjustable
shunt regulators with guaranteed thermal stability over
a full operation range. These ICs feature sharp turn-on
characteristics, low temperature coefficient and low
output impedance, which make them ideal substitutes
for Zener diodes in applications such as switching
power supply, charger and other adjustable regulators.
The output voltage of these ICs can be set to any value
between V
REF
(2.5V) and the maximum cathode volt-
age (36V).
The AN431 precision reference is offered in two volt-
age tolerance: 0.5% and 1.0%.
These ICs are available in SOT-23 package.
