Procurement Notes

Verify the specific suffix and tape-and-reel specifications against the official datasheet before procurement. Confirm that the SOT-23-3 package dimensions align with your PCB footprint requirements. Ensure the selected variant meets the required thermal management standards for your intended operating environment. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when a low-voltage, high-accuracy shunt regulator is required in a small form factor. Consider the 1% initial accuracy and 138 PPM/C temperature coefficient for precision applications. Evaluate the 80 mA maximum shunt current capability against your circuit load requirements. Ensure the -40°C to +125°C operating range matches your environmental conditions.

Part Context

This device belongs to the TLVH431A series of low-voltage adjustable precision shunt regulators. It serves as a modern alternative to traditional Zener diodes, offering superior stability and lower noise. The series is designed for applications where space constraints and voltage precision are critical factors in system design.

Replacement Considerations

Check for direct pin-compatible alternatives within the same family, such as the TLVH431AQDBZT for automotive qualification or other variants in the TLVH431 series. Verify that any substitute maintains the same SOT-23-3 package and electrical characteristics.
