component
L78L18ACUTR
Public Made by Adomby adom
STMicroelectronics Voltage Regulators - Linear, Low Drop Out (LDO) Regulators, SOT-89-3. 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 497-7280-2-ND, LCSC_PN C2802523, MOUSER_PN 511-L78L18ACU). 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.
