component
LD3985M33R
Public Made by Adomby adom
STMicroelectronics Voltage Regulators - Linear, Low Drop Out (LDO) Regulators, SOT-23-5L. 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 497-3504-2-ND, LCSC_PN C46243, MOUSER_PN 511-LD3985M33R). 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.
