AME AME431BAJEVB12Z Adjustable precision shunt regulator Datasheet

AME, Inc.
AME431B
n 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 output impendance, which make them ideal substitutes for
Zener diodes in applications such as switching power
supply, charger and other adjustable regulators.

n Functional Block Diagram
V+ (Cathode)
REF
The reference is set to 1.24V for AME431Bxxxxx12 and
2.5V for AME431Bxxxxx25. The output voltage can be
set to 1.24V to 16V for VREF=1.24V part type and 2.5 to
36V for VREF=2.5V part type with two external resistors.
VREF
The AME431B precision reference is offered in two reference tolerance: 0.5% and 1.0%
The 5 main packages have low thermal impendance
GND (Anode)
which allows operation over a wide range of -40oC t o
+125oC.
