I'm trying to build a circuit around the LM2575 step-down voltage regulator which has five, stepped pins on a TO-220 package. Sadly it's not a part that's in the program but are there any packages that use that footprint? I'm working on adding the component myself but I'm having trouble with editing an existing model for my purposes. I think I've almost got the .svg file for PCB pads worked out but nothing more.
Have I missed any similar parts?
