Procurement Notes

Verify the complete part number including suffixes to ensure correct output voltage and package type. Confirm RoHS compliance status through official manufacturer documentation. Check for obsolescence notices as availability may vary. Ensure ordering quantities align with standard reel packaging requirements specified by the supplier.

Selection Notes

Select this component when a fixed 3.1 V output is required with high current capability. Consider the SOT-23-5 package constraints for thermal management at full load. Evaluate input voltage ranges to ensure sufficient headroom for the specified dropout characteristics. Compare line and load regulation specs against circuit sensitivity requirements.

Part Context

This component belongs to the S-816 series of CMOS LDO regulators from ABLIC. The series is characterized by low quiescent current and high output current capabilities. It serves as a power management integrated circuit (PMIC) designed for portable applications where space and energy efficiency are critical design parameters.

Replacement Considerations

Direct substitutes must match the 3.1 V output, 1 A current rating, and SOT-23-5 package. Verify pin compatibility and thermal performance. Cross-reference with other ABLIC S-816 variants if voltage or package differences are acceptable.
