description
The TL431 and TL431A are three-terminal
adjustable shunt regulators with specified thermal
stability over applicable automotive, commercial,
and military temperature ranges. The output
voltage can be set to any value between Vref
(approximately 2.5 V) and 36 V, with two external
resistors (see Figure 17). These devices have a
typical output impedance of 0.2
. Active output
circuitry
provides
a
very
sharp
turn-on
characteristic, making these devices excellent
replacements
for
Zener
diodes
in
many
applications,
such
as
onboard
regulation,
adjustable power supplies, and switching power
supplies.
The TL431C and TL431AC are characterized for
operation from 0
°C to 70°C, and the TL431I and
TL431AI are characterized for operation from
–40
°C to 85°C.
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of
