Programmable Shunt Regulator
KA431S, KA431SA, KA431SL
Description The KA431S / KA431SA / KA431SL are three−terminal adjustable
regulator series with a guaranteed thermal stability over the operating temperature range. The output voltage can be set to any value between VREF (approximately 2.5 V) and 36 V with two external resistors. These devices have a typical dynamic output impedance of 0.2 W. Active output circuitry provides a sharp turn−on characteristic, making these devices excellent replacement for zener diodes in many applications.
Features
• Programmable Output Voltage to 36 V • Low Dynamic Output Impedance 0.2 W (Typical) • Sink Current Capability: 1.
