Texas Instruments Voltage Regulators - Linear, Low Drop Out (LDO) Regulators, SOT-223-4. Pinout extracted from the datasheet, KiCad symbol/footprint/3D.

Ray
symbol: bind pad 4 (OUT), which had no pin. The footprint carries the pad and page.json described it as "Tab", but no symbol pin resolved to it - so KiCad emitted no connection and the pad was inert copper in Fusion. On this part that pad is the thermal path. Name and type taken from the page's own entry; the entry is renumbered to the pad the footprint actually has, so page, symbol and footprint agree.
