TL432LI - Programmable Shunt Regulator

Download the TL432LI datasheet PDF. This datasheet also covers the TL431LI variant, as both devices belong to the same programmable shunt regulator family and are provided as variant models within a single manufacturer datasheet.

General Description

The TL431LI device is a three-terminal adjustable shunt regulator, with specified thermal stability over applicable automotive, commercial, and military temperature ranges.

The output voltage can be set to any value between Vref (approximately 2.495 V) and 36 V, with two external resistors.
