KA431LDTF

Programmable Shunt Regulator KA431A, KA431L Description The KA431A and KA431L are three−terminal adjustable regulators 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. www.onsemi.com Features • • • • • • • 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 (Typical) Temperature Compensated for Operation Over Full Rated Operating Temperature Range Low Output Noise Voltage Fast Turn−on Response 12 1 3 TO−92 CASE 135AN 2 3 TO−92 CASE 135AR MARKING DIAGRAM KA 431XX ALYW KA431XX A L YW = Specific Device Code = Assembly Location = Wafer Lot = Assembly Start Week PIN CONNECTIONS Figure 1.
