TL431 Programmable Precision References

The TL431 integrated circuits are three-terminal

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.

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 Ω. The

characteristics of these references make them

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.
