TLVH431BIDBVR

Overview

The TLVH431BIDBVR is a low-voltage adjustable precision shunt regulator manufactured by Texas Instruments. It operates within an input 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 ±0.5% and a temperature coefficient of 138 ppm/°C. It supports a maximum cathode current of 100 mA and functions across a temperature range of -40°C to +85°C. Packaged in a compact SOT-23-5 surface-mount case, it serves as a high-performance reference for power management applications.

Feature Summary

• Adjustable output voltage capability spanning from 1.24 V up to the maximum supply limit
• High precision performance with ±0.5% initial accuracy tolerance
• Wide operating current range supporting up to 100 mA cathode current
• Robust thermal stability with a specified temperature coefficient of 138 ppm/°C

Applications

• Precision voltage references in battery-powered equipment
• Programmable linear and switching power supplies
• Over-voltage protection circuits
• Remote sensing feedback loops

Procurement Notes

Verify the specific suffix 'IDBVR' to confirm the ±0.5% accuracy grade and industrial temperature range (-40°C to +85°C). Ensure the ordering part number matches the required SOT-23-5 package configuration. Confirm RoHS compliance status through official manufacturer documentation prior to procurement integration.

Selection Notes

Select this component when precise voltage referencing is required in space-constrained designs utilizing the SOT-23-5 footprint. It is suitable for applications demanding higher current handling than standard 20 mA shunt regulators while maintaining tight accuracy tolerances. Evaluate the 138 ppm/°C temperature coefficient against system thermal requirements.

Part Context

This device belongs to the TLVH431 family of low-voltage adjustable shunt regulators. It offers improved performance over legacy TL431 devices, including lower noise and wider operating current ranges. The family is designed for general-purpose voltage regulation and reference applications in modern electronic systems requiring compact surface-mount solutions.

Replacement Considerations

Direct replacements include the TLVH431BIDBVT (same electrical specs, different package) or the TLVH431AIDBVR (±1% accuracy). Cross-manufacturer equivalents such as the AS431BKTR-G1 may be considered if pin compatibility and electrical parameters are verified.
