General Description
The AME431B series ICs are 3-terminal adjustable
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 reference is set to 1.24V for AME431Bxxxxx12.
The output voltage can be set to 1.24V to 16V for
V REF =1.24V part type with two external resistors.
The AME431B precision reference is offered in two ref-
erence tolerance: 0.5% and 1.0%
The 5 main packages have low thermal impendance
which allows operation over a wide range of
-40℃ to +125℃.
