Hello, my Name is Philip and i am doing a internship at the laboratory of Elektor in Limbricht. When i saw Raymond's 7805 project i was excited about it. So i wanted to make it cheaper and started to creating a through-hole version. The project includes 2 one-sided PCB's. One is an adapter from a 16-QFN to an 8-DIL Footprint. The second PCB contains the rest on a size of 22mm x 24mm. Both Inductors will be mounted from the backside of the other components.
