TL431 Series  
BIPOLAR LINEAR INTEGRATED CIRCUIT  
TECHNICAL DATA  
PROGRAMMABLE PRECISION REFERENCES  
The TL431 Series integrated circuits are three-terminal programmable shunt regulator diodes.  
These monolithic IC voltage reference 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 Series  
operates as a shunt regulator, it can be used as either a positive or negative voltage reference.
