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 Ω. 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 Ω (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
