TLVH431ACPKG3

Overview

The TLVH431ACPKG3 is a low-voltage adjustable precision shunt regulator manufactured by Texas Instruments. It operates with an input voltage range up to 20 V and provides an adjustable output voltage from 1.24 V to 18 V. The device features an initial accuracy of 1% and a maximum temperature coefficient of 161 ppm/°C. It supports a maximum cathode current of 70 mA and functions within a temperature range of -40°C to +125°C. The component is housed in a SOT-89-3 surface-mount package.

Feature Summary

Adjustable reference voltage capability across a wide operational range
Precision regulation with defined initial accuracy specifications
Extended industrial temperature rating for harsh environments

Applications

Battery-powered equipment requiring precise voltage monitoring
Portable devices utilizing low-voltage power supplies
General-purpose voltage references in compact designs

Procurement Notes

Verify the specific suffix against official manufacturer documentation to confirm pinout compatibility and electrical tolerances. Ensure the sourcing channel provides valid traceability for automotive or industrial grade requirements. Confirm RoHS compliance status through current datasheets before integration into production schedules.

Selection Notes

Select this component when a low-profile surface-mount solution is required for precision shunt regulation. Compare the 70 mA cathode current limit against circuit load requirements. Evaluate the 161 ppm/°C temperature coefficient against system stability needs compared to higher-grade alternatives.

Part Context

This part belongs to the TLVH431 family of low-voltage adjustable precision shunt regulators. It serves as a direct replacement for standard TL431 devices in applications where lower operating voltages and smaller form factors are prioritized. The family maintains compatibility with common feedback loop configurations while optimizing performance for modern portable electronics.

Replacement Considerations

Publicly confirmed substitute part numbers include TLVH431AQPKG3 and TLVH431QPKG3. Verify that alternative suffixes match the required accuracy and temperature specifications.
