Description
The TL431/TL431A are 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 0.2Ω. Active output circuitry
provides a very sharp turn-on characteristic, making these
devices excel lent replacement for zener diodes in many
applications.
