TLV431IDBVRE4

Overview

The TLV431IDBVRE4 is a low-voltage adjustable precision shunt regulator manufactured by Texas Instruments. It operates within a supply voltage range of 2.5 V to 36 V and provides an adjustable output voltage from 1.24 V to 36 V. The device features an initial accuracy of 1% and a temperature coefficient of 92 ppm/°C. Maximum cathode current is 100 mA, with a minimum operating current of 80 µA. It functions across a temperature range of -40°C to +125°C and is housed in an SOIC-8 package.

Feature Summary

• Adjustable reference voltage capability spanning from 1.24 V up to the maximum supply limit
• High thermal stability characterized by a low temperature coefficient of 92 ppm/°C
• Wide operational current range supporting both low quiescent and high load conditions

Applications

• Precision voltage reference sources for analog-to-digital converter circuits
• Programmable linear power supply regulation loops
• Comparator threshold setting networks in signal conditioning systems

Procurement Notes

Verify component authenticity through authorized distribution channels due to widespread counterfeiting risks in the market. Confirm RoHS compliance status and specific tape-and-reel packaging requirements prior to procurement. Ensure that the ordering suffix matches the required package type and environmental rating specifications for the target application.

Selection Notes

Select this component when a wide input voltage range and high accuracy are required in surface-mount designs. The SOIC-8 package offers thermal performance advantages over smaller alternatives. Consider the 1% initial tolerance for applications demanding tight voltage regulation without external trimming circuitry.

Part Context

This part belongs to the TL431 family of programmable zener diodes, widely used as voltage references and error amplifiers. The TLV431 variant specifically optimizes performance for lower voltage applications while maintaining compatibility with standard three-terminal regulator topologies. The RE4 suffix indicates lead-free construction compliant with modern environmental standards.

Replacement Considerations

Direct pin-compatible substitutes include the TLV431IDBVR and TLV431IDBVT. Verify that alternative packages maintain identical electrical characteristics and thermal dissipation capabilities for seamless integration.
