The TL431, A, B integrated circuits are three ? terminal
programmable shunt regulator diodes. These monolithic IC voltage
http://onsemi.com
references operate as a low temperature coefficient zener which is
programmable from V ref 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 W . 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.

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