DESCRIPTION

The TL431 is a three-terminal adjustable regulator series with a guaranteed thermal stability over

applicable temperature ranges. The output voltage may be set to any value between Vref

(approximately 2.5 volts) and 36 volts with two external resistors. These devices have a typical

dynamic output impedance of 0.2 . Active output circuitry provides a very sharp turn-on

Ω

characteristic, making these devices excellent replacement for zener diodes in many applications.

The TL431 is characterized for operation from 0^oC to +70^oC.
