DESCRIPTION
The KK431 is a 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 40 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 excellent replacement for zener diodes in many applications.
