Procurement Notes

Verify the specific suffix codes against official ABLIC documentation to confirm pinout and electrical characteristics. Confirm availability status as this part may be subject to discontinuation notices. Ensure compatibility with existing PCB footprints and thermal requirements before procurement. Cross-reference ordering information with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when a fixed 3.5 V output is required with high current capacity. Consider the SOT-23-5 package constraints for thermal dissipation. Evaluate input voltage ranges to ensure sufficient headroom for the specified dropout voltage. Verify that the 2% accuracy meets system tolerance requirements compared to other LDO options.

Part Context

This regulator is part of the S-816 series from ABLIC, which focuses on low-power linear regulators. The series is characterized by ultra-low current consumption and small package sizes. The S-816A variant specifically offers higher output current capabilities compared to lower-current counterparts in the same family, targeting applications where efficiency and size are critical.

Replacement Considerations

Check for direct replacements within the S-816 series with different output voltages or packages. Verify if newer revisions of the S-816 series offer improved specifications or updated packaging. Consult ABLIC's official replacement guide for end-of-life notifications and recommended alternative part numbers.
