TL431ACLPE3

Overview

The TL431ACLPE3 is an adjustable precision shunt regulator manufactured by Texas Instruments. It provides a reference voltage range from 2.495V to 36V with an initial accuracy of ±1%. The device supports a maximum cathode current of 100mA and operates within a temperature range of 0°C to 70°C. It utilizes a TO-92-3 through-hole package.

Feature Summary

• Provides stable adjustable reference voltage for power supply regulation
• Ensures high precision with tight initial accuracy tolerance
• Supports low minimum cathode current operation

Applications

• Precision power supplies
• Voltage regulators
• Remote sense circuits
• DC-to-DC converters

Procurement Notes

Verify the specific suffix 'E3' indicates RoHS compliance and lead-free construction as per manufacturer documentation. Confirm the package type matches the required PCB footprint. Check current part status, as availability may vary across distributors. Ensure the operating temperature range meets system requirements.

Selection Notes

Select this component when a precise, adjustable voltage reference is needed in a through-hole configuration. The ±1% accuracy suits applications requiring tighter tolerances than standard variants. Consider the thermal performance within the specified operating range during circuit design.

Part Context

This device belongs to the TL431 family of programmable shunt regulators. It serves as a versatile alternative to Zener diodes, offering superior performance in terms of accuracy and temperature stability. The TO-92 package facilitates easy integration into legacy and new designs.

Replacement Considerations

Compatible substitutes include TL431ACLP and TL431ACLPR. Verify pinout compatibility and electrical specifications before substitution.
