The TL431 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 volts with two external resistors. These devices
exhibit a wide operating current range of 1.0 to 100mA
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 volt reference makes it
convenient to obtain a stable reference from 5.0 volt
logic supplies, and since the TL431 operates as a shunt
regulator, it can be used as either a positive or negative
voltage reference.

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