View Datasheet Manufacturer Site View Pricing & Stock

The KA431 / KA431A / KA431L are three-terminal adjustable regulators with a guaranteed thermal stability over the operating temperature ranges. The output voltage may be set to any value between VREF (approximately 2.5V) and 36V with two external resistors. These devices have a typical dynamic output impedance of 0.2 Ω. Active output circuitry provides a very sharp turn-on characteristic, making these devices excellent replacements for Zener diodes in many applications.
