KA431 - Programmable Shunt Regulator

This page provides the datasheet information for the KA431, a member of the KA4 Programmable Shunt Regulator family.

Datasheet Summary

Description

The KA431 / KA431A / 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.

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.
