Part Review and Datasheet Verification

Review all available part information (MPN, package, pin count, description, properties). If no datasheet URL is already set, search the web for the official datasheet and update the part's Datasheet property with the URL. Then cross-check the schematic symbol, footprint, and pin descriptions against the datasheet. Summarize key specs and flag any mismatches.

flux

I’ll inspect the part metadata, look for an official datasheet if needed, then verify symbol pins/footprint/pin descriptions against it and update the Datasheet property if it’s missing.

flux

The part already has a Datasheet URL set, so I’m using that linked ON Semiconductor datasheet for verification.

Completed the part review and saved the detailed findings in part-review-ncp785ah120t1g.
Key flags: the Datasheet URL was already set; the part matches NCP785AH120T1G 12 V SOT-89 regulator, but the project description appears to have a quiescent-current typo (15A vs µA), PSRR wording mismatch, overly broad package property (TO vs SOT-89-3), and missing/unspecified pin descriptions/types. The 4th pad is acceptable if it represents the GND tab, but it should be clearly labeled as Tab / GND and tied to GND.
