Description
The GS431B/TL431A/TL431 are 3-terminal adjustable
precision shunt regulators with guaranteed temperature
stability
over
the
applicable
extended
commercial
temperature range. The output voltage may be set at any
level greater than 2.495V (VREF) up to 30V merely by
selecting two external resistors that act as a voltage divider
network. These devices have a typical output impedance of
0.08
. Active output circuitry provides very sharp turn-on
characteristics, making these devices excellent improved
replacements for zener diodes in many applications.
The precise ±0.5% reference voltage tolerance of the
GS431B makes it possible in many applications to avoid
the use of a variable resistor, consequently saving cost and
eliminating
drift and reliability problems associated with it.
