component
LD1117AS18TR
Public Made by Adomby adom
STMicroelectronics Voltage Regulators - Linear, Low Drop Out (LDO) Regulators, SOT-223-3. 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> (DIGIKEY_PN 497-1226-2-ND, LCSC_PN C2845037, MOUSER_PN 511-LD1117AS18). 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.
