Procurement Notes

Verify the specific suffix 'PK' corresponds to the SOT-89-3 package configuration as documented in official Texas Instruments datasheets. Confirm RoHS compliance status and lead times through authorized distributors. Ensure design compatibility with the 70 mA sink current limit and 18 V maximum voltage rating during integration planning.

Selection Notes

Select this component when precise low-voltage referencing is required in compact designs. The SOT-89-3 package offers a balance between thermal performance and board space efficiency. Consider the 0.5% accuracy and 161 ppm/°C temperature coefficient for applications demanding stability over varying environmental conditions without active compensation.

Part Context

This part belongs to the TLVH431 family of low-voltage adjustable precision shunt regulators. It serves as a cost-effective alternative to traditional Zener diodes, offering superior temperature stability and lower dynamic impedance. The family includes variants with different accuracies and packages, catering to diverse industrial and consumer electronics requirements.

Replacement Considerations

Compatible substitutes include TLVH431AIPK (1% accuracy) or TLVH431MIPK (1.5% accuracy) for relaxed tolerance needs. For automotive applications, consider the TLVH431BQ series. Verify pinout compatibility and thermal characteristics before substituting.
