n General Description
shunt regulator with guaranteed temperature stability over
a full operation range. These ICs feature sharp turn-on
characteristics, low temperature coefficient and low out-
put impendance, which make them ideal substitutes for
Zener diodes in applications such as switching power
supply, charger and other adjustable regulators.
The output voltage can be set to 1.24V to 16V for
V
erence tolerance: 0.5% and 1.0%
which allows operation over a wide range of -40
+125
Rev.E.05
AME431B-1.24V
REF
The reference is set to 1.24V for AME431Bxxxxx12.
n Features
The AME431B series ICs are 3-terminal adjustable
The AME431B precision reference is offered in two ref-
The 5 main packages have low thermal impendance
=1.24V part type with two external resistors.
