DESCRIPTIOON
The AP431 is a low voltage three terminal
adjustable shunt regulator with a guaranteed thermal
stability over applicable temperature ranges. The output
voltage can be set to any value between V
REF
(approximately 2.5 V) to 18V with two external resistors
(see application circuit). This device has a typical output
impedance of 0.2
Ω
. Active output circuitry provides a
very sharp turn on characteristic, making this device
excel lent replacement for Zener diodes in many
applications.
o
The AP431 is characterized for operation from 0 C
to 105
o
C, and four package options (SOT-23, SOT-89,
SO-8 and TO-92) allow the designer the opportunity to
select the proper package for their application.
