The TL431, A, B integrated circuits are three–terminal programmable
shunt regulator diodes. These monolithic IC voltage references operate as a
low temperature coefficient zener which is programmable from Vref to 36 V
with two external resistors. These devices exhibit a wide operating current
range of 1.0 mA to 100 mA with a typical dynamic impedance of 0.22 . The
characteristics of these references make them excellent replacements for
zener diodes in many applications such as digital voltmeters, power
supplies, and op amp circuitry. The 2.5 V reference makes it convenient to
obtain a stable reference from 5.0 V logic supplies, and since the TL431, A,
B operates as a shunt regulator, it can be used as either a positive or
negative voltage reference.

SOP–8 is an internally modified SO–8 package. Pins 2,
3, 6 and 7 are electrically common to the die attach flag.
This internal lead frame modification decreases power
dissipation capability when appropriately mounted on a
printed circuit board. SOP–8 conforms to all external
dimensions of the standard SO–8 package.
