Precision References  
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 V to 36 V with two external resistors. These  
ref  
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.
