ADJUSTABLE PRECISION ZENER SHUNT REGULATOR

TA 431

DESCRIPTION

The TA431 is a three-terminal adjustable regulator with a guaranteed thermal stability over

REF

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

(approximately 2.5V) and 36V with two external resistors. This device has typical dynamic output

impedance of 0.2Ω. Active output circuitry provides a very sharp turn-on characteristic, making

these devices excellent replacement for zener diodes in many applications.
