DESCRIPTION
The TL431/TL431A/TL431B series
precision adjustable three terminal
shunt voltage regulators are pin-to-pin
compatible with the industry standard
TL431. The output voltage of this
reference is programmable by using
two external resistors from 2.5V to
36V. These devices offer low output
impedance
for
improved
load
regulation.
The
typical
output
impedance of these devices is 200m.
These devices find application in the
feedback path of switching power
supplies,
OVP
crowbar
circuits,
reference for A/D, D/A, and as zener
diodes
with
improved
turn-on
characteristics.
