Procurement Notes

Verify the specific suffix (e.g., ILPR) against the manufacturer's latest datasheet to confirm exact accuracy grade and package variant. Check for product discontinuance notifications or lifecycle status updates prior to finalizing procurement plans. Ensure compatibility with existing PCB footprints and thermal requirements during integration.

Selection Notes

Select this component when low-voltage operation and precise shunt regulation are required in compact designs. Consider the 0.5% or 1% accuracy grades based on circuit tolerance needs. Evaluate the SOT-23-5 package constraints against available board space. Confirm that the 80 mA sink current capability meets the load requirements of the target application.

Part Context

The TLVH431 series represents a family of low-power adjustable shunt voltage references. It serves as a modern alternative to traditional three-terminal references, offering improved performance in low-voltage environments. The series includes various accuracy grades and package options to support diverse industrial and consumer electronics applications requiring stable voltage referencing.

Replacement Considerations

Cross-reference with other TLVH431 variants for different accuracy grades or packages. Verify pinout compatibility if substituting with similar shunt regulators from other manufacturers. Check for any specific EOL notices affecting supply chain continuity.
