component
AMS1117CD-5.0
Public Made by Adomby adom
UMW Voltage Regulators - Linear, Low Drop Out (LDO) Regulators, TO-252-2. Pinout extracted from the datasheet, KiCad symbol/footprint/3D.

orderable attributes: rebuild .lbr with adom-lbr 2.18.0 so MPN, MANUFACTURER and the distributor part numbers reach <technology> (LCSC_PN C347250). The published library carried no attributes at all, so a BOM had nothing to buy from. Distributor PNs matched on exact MPN AND corroborating manufacturer.
