The KA431S / KA431SA / KA431SL are three-terminal
adjustable regulator series with a guaranteed thermal
stability over the operating temperature range. The out-
put voltage can be set to any value between V REF
(approximately 2.5 V) and 36 V with two external resis-

? Temperature Compensated for Operation Over
Full Rated Operating Temperature Range
? Low Output Noise Voltage
? Fast Turn-on Response
tors. These devices have a typical dynamic output
impedance of 0.2 Ω . Active output circuitry provides a
sharp turn-on characteristic, making these devices
excellent replacement for Zener diodes in many applica-
tions.
