by BL(上海贝岭)BL1117-33CX is a BL surface-mount voltage regulator in the 1117 family, used to provide a regulated supply on a PCB. Its SOT-223 package has leads and a tab represented by four symbol pins and four footprint pads. The download contains a KiCad symbol, the SOT-223-4_L6.5-W3.5-P2.30-LS7.0-BR footprint, and a 3D model for checking placement. Check the pad mapping and copper around the tab when integrating it into a board. These files came from a real ProtoFlow import that was converted and checked in the editor. You can open this part directly in ProtoFlow.
