component
ZLDO1117QG33TA
Public Made by Adomby adom
Diodes Incorporated Voltage Regulators - Linear, Low Drop Out (LDO) Regulators, SOT-223. 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 C326523). 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.
