Procurement Notes

This specific part number is officially listed as End-of-Life (EOL) by the manufacturer. Distribution channels indicate that sales are currently restricted or unavailable in certain regions. Buyers must verify active lifecycle status before design inclusion. Alternative sourcing may require checking for discontinued stock or authorized distributors handling legacy inventory. Confirm compliance documentation availability separately.

Selection Notes

Engineers should evaluate this component against current production alternatives due to its discontinued status. The 300 mA output current and SOT-23-5 form factor define its physical and electrical constraints. Verify thermal dissipation requirements for the target application environment. Consider pin-compatible successors from the same manufacturer family if long-term supply stability is required for mass production.

Part Context

This regulator belongs to the ABLIC S-816 series, which focuses on low-power linear regulation solutions. The series typically targets applications where noise performance and simplicity are prioritized over switching efficiency. The S-816A variant specifically denotes particular internal reference and control characteristics within the broader product line.
