n DESCRIPTION
The AIC431/TL431A/TL431 are 3-terminal a djustable precision shunt
regulators with guaranteed temperature stability over the applicable extended commercial temperature range.
The output voltage may be set at any level greater than 2.
495V (V REF) up to 30V merely by selecting two external resistors that act as a voltage divider network.
These devices have a typical output impedance of 0.
08Ω .
Active output circuitry provides a very sharp turn-on characteristics, making these devices excellent improved replacements for zener diodes in many applications.
The precise ±0.
5% reference voltage tolerance of the ...
