TL1431M - Precision Programmable Reference

Download the TL1431M datasheet PDF. This datasheet also covers the TL1431 variant, as both devices belong to the same precision programmable reference family and are provided as variant models within a single manufacturer datasheet.

General Description

The TL1431 device is a precision programmable reference with specified thermal stability over automotive, commercial, and military temperature ranges.

The output voltage can be set to any value between VI(ref) (approximately 2.5 V) and 36 V with two external resistors (see Figure 25).

Key Features

  • 1 0.4% Initial Voltage Tolerance.
  • 0.2-Ω Typical Output Impedance.
  • Fast Turnon (500 ns).
  • Sink Current Capability (1 mA to 100 mA).
  • Low Reference Current (REF).
  • Adjustable Output Voltage (VI(ref) to 36 V) 2.
