TL431CL3T

Overview

The TL431CL3T is an adjustable shunt voltage reference manufactured by STMicroelectronics. It provides a programmable output voltage ranging from 2.495 V to 36 V, set via two external resistors. The device operates within a cathode current range of 1 mA to 100 mA and features an initial accuracy of 2%. It is housed in a surface-mount SOT-23 package with three pins. The component supports operation at temperatures between 0 °C and 70 °C, with a maximum input voltage of 37 V.

Feature Summary

Adjustable output voltage capability spanning 2.495 V to 36 V
Guaranteed temperature stability across the operating range
Wide cathode current operation from 1 mA to 100 mA

Applications

Precision power supply regulation
On-line digital logic supplies
Voltage references for operational amplifiers

Procurement Notes

Verify the specific suffix CL3T against official STMicroelectronics documentation to confirm the commercial temperature grade and tape-and-reel packaging format. Ensure the ordering code matches the required pin configuration and compliance standards before procurement.

Selection Notes

Select this component when a compact SOT-23 footprint is required for adjustable voltage referencing. Confirm that the commercial temperature range meets system requirements, as automotive variants offer extended thermal performance.

Part Context

This part belongs to the TL431 family of programmable shunt regulators. These devices function similarly to Zener diodes but offer superior precision and adjustability. The TL431 series is widely used in feedback loops for switching power supplies and linear regulators.

Replacement Considerations

Compatible substitutes include the TL431CDT (SOIC-8 package) and TL431IL3T (extended temperature range). Verify pinout compatibility and electrical specifications before substitution.
