Shanghai Siproin Microelectronics SSP7785 5 0V Voltage Regulators - Linear, Low Drop Out (LDO) Regulators, ESOP-8. 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 C2845052). 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.
add symbol pin "9" for the exposed thermal pad: the footprint carries the pad and the symbol had none, so it reached no net (vendor string 'ESOP-8' denotes an exposed pad)
fix footprint: SOIC-8-1EP_3.9x4.9mm_P1.27mm_EP2.41x3.3mm -> SOIC-8-1EP_3.9x4.9mm_P1.27mm_EP2.41x3.3mm (3d refresh; body regenerated from the footprint F.Fab outline)
