KA431-Programmable Shunt Regulator
It shows that the KA431/KA431A/KA431L has a three-terminal adjustable voltage regulator series, and the thermal stability is more guaranteed for the applicable temperature range. The output voltage can be set to any value between VREF (approximately 2.5 volts) and two external resistors of 36. These devices have a voltage typical of 0.2 watts for an active output. The dynamic output impedance circuit provides a very sharp steering characteristic for making These devices are excellent for Zener diode replacement in many applications.
Features • Programmable output voltage of 36 volts • Low dynamic output impedance 0.20 typical • Sink current capability from 1.0 to 100mA
• Equivalent full-scale temperature coefficient 50ppm/°C typical 50ppm • Temperature compensated operation over rated full operating temperature range • Low output noise voltage • Fast turn-on response
