TL431K - three-terminal adjustable regulator

Download the TL431K datasheet PDF. This datasheet also covers the TL431 variant, as both devices belong to the same three-terminal adjustable regulator family and are provided as variant models within a single manufacturer datasheet.

General Description

The UTC TL431 is a three-terminal adjustable regulator with a guaranteed thermal stability over applicable temperature ranges.

The output voltage may be set to any value between VREF (approximately 2.5V) and 36V with two external resistors.

Key Features

  • S.
  • Programmable output Voltage to 36V.
  • Low dynamic output impedance 0.2Ω.
  • Sink current capability of 1.0 to 100mA.
  • Equivalent full-range temperature coefficient of 50ppm/°C typical for operation over full rated operating temperature range.
