TL1431IZT

Overview

The TL1431IZT is an adjustable shunt voltage reference manufactured by STMicroelectronics. It provides a guaranteed temperature-stable reference voltage across the operating range. The output voltage is programmable between 2.5 V and 36 V using two external resistors. The device supports a cathode current range from 1 mA to 100 mA with a typical dynamic impedance of 0.2 Ω. It is housed in a TO-92-3 package and operates within a temperature range of -40 °C to +125 °C.

Feature Summary

Adjustable output voltage settable between 2.5 V and 36 V via external resistors
Wide sink current capability ranging from 1 mA to 100 mA
Guaranteed temperature stability over the entire specified operating range

Applications

Precision power supply regulation
Programmable linear regulators
Battery chargers
DC-to-DC converters

Procurement Notes

Verify the specific suffix 'IZT' against the manufacturer's official datasheet to confirm the exact tolerance grade, temperature rating, and packaging configuration. Ensure the procurement documentation matches the required automotive or industrial specifications defined for this part number variant.

Selection Notes

Select this component when a stable, adjustable shunt reference is required for circuits operating between 2.5 V and 36 V. Consider the TO-92-3 through-hole package for prototyping or applications where surface-mount options are unsuitable. Verify that the 100 mA sink current meets the load requirements.

Part Context

This part belongs to the TL1431 series of programmable shunt voltage references. It serves as a high-performance alternative to standard TL431 devices, offering improved precision and extended temperature ranges suitable for demanding automotive and industrial environments.
