Programmable Shunt Regulator KA431A, KA431L 1 2 1 3 2 3
Description TO−92 TO−92
The KA431A and KA431L are three−terminal adjustable regulators
CASE 135AN CASE 135AR
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 replacements for Zener diodes in many applications. KA 431XX
Features
ALYW • Programmable Output Voltage to 36 V • Low Dynamic Output Impedance: 0.2 W (Typical) • Sink Current Capability: 1.0 to 100 mA • Equivalent Full−Range Temperature Coefficient of 50 ppm/°C KA431XX = Specific Device Code (Typical) A = Assembly Location • Temperature Compensated for Operation Over Full Rated L = Wafer Lot Operating Temperature Range YW = Assembly Start Week • Low Output Noise Voltage
PIN CONNECTIONS
• Fast Turn−on Response 1 − Ref 2 − Anode 3 − Cathode 1 2 3 1 2 3
