E T - TL431
Adjustable Precision Shunt Regulator
‹ Description
The ET 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 and 36 volts with
two external resistors. These device
have a typical dynamic output
impedance of 0.27Ω, Active output
circuitry provides a very sharp
turn-on characteristic, making these
devices excellent replacement for
zener diodes in many applications.
