CASE 318AB Description DEVICE MARKING INFORMATION
The KA431S / KA431SA / KA431SL are three−terminal adjustable See general marking information in the device regulator series with a guaranteed thermal stability over the operating marking section on page 2 of this data sheet. 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.
ORDERING INFORMATION
Active output circuitry provides a sharp turn−on characteristic, making these devices excellent replacement for zener diodes in many See detailed ordering and shipping information on page 6 of this data sheet. applications.
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 • These Devices are Pb−Free and Halogen Free REFERENCE CATHODE + − 2.5 Vref ANODE CATHODE (K) REFERENCE (R) ANODE(A)
