TL431CL5T

Overview

The TL431CL5T is an adjustable shunt voltage reference manufactured by STMicroelectronics, housed in a SOT-23-5 surface-mount package. It provides an output voltage range from 2.495 V to 36 V, set via two external resistors. The device operates with a cathode current range of 1 mA to 100 mA and features a typical dynamic impedance of 0.22 Ω. Initial accuracy is specified at ±2.21%, with a temperature coefficient of 100 ppm/°C. It supports industrial operating temperatures from 0°C to +70°C and complies with RoHS3 standards.

Feature Summary

Adjustable output voltage programmable between 2.5 V and 36 V using external resistors
Wide sink current capability ranging from 1 mA to 100 mA for flexible circuit design
Guaranteed temperature stability over the entire specified operating temperature range

Applications

Power supply regulation circuits
Industrial control systems
Automotive electronics applications

Procurement Notes

Verify component authenticity through authorized STMicroelectronics distributors or certified partners. Confirm that the received parts match the specific TL431CL5T designation, including the SOT-23-5 package and ±2.21% tolerance variant. Ensure compliance with RoHS3 environmental standards as documented in official specifications before integration into production.

Selection Notes

Select this component when a compact surface-mount solution is required for precision voltage referencing within the 2.5 V to 36 V range. The SOT-23-5 package offers space efficiency compared to larger alternatives. Consider the ±2.21% initial accuracy and 100 ppm/°C temperature coefficient for applications requiring moderate precision without the cost of higher-grade variants like the TL1431 series.

Part Context

This part belongs to the TL431 family of programmable shunt voltage references, widely used as a low-cost alternative to Zener diodes. The TL431CL5T specifically denotes the commercial grade (0°C to +70°C) with standard accuracy, distinguishing it from automotive or high-precision versions within the same product line.
