Description
The TL431/TL431A are three-terminal adjustable regulator
series with a guaranteed thermal stability over applicable
temperature ranges. The output voltage may be set to any
value between V
REF
(approximately 2.5 volts) and 36 volts
with two external resistors These devices have a typical
dynamic output impedance of 0.2
Ω
. Active output circuitry
provides a very sharp turn-on characteristic, making these
devices excel lent replacement for zener diodes in many
applications.
