Description
The KA431S/KA431SA/KA431SL 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 V
(approximately 2.5 volts) and 36 volts with two external
resistors These devices have a typical dynamic output
impedance of 0.2
sharp turn on characteristic, making these devices excellent
replacement for zener diodes in many applications.
