TL431, A, B Series,

NCV431A, B

Programmable

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

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

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.
