Thanks Puffin. It was quite a while ago when I initially toyed with the idea of a PCB for the Reg Booster. Ant deserves some credit for nagging me to death to finish it off then he eventually took it upon himself to re-design the whole thing, with a little help from me
The reg on the back was something we discussed having seen it done on a couple of other fancy 3-pin reg replacements. That wasn't really our idea but something we copied, I thin it was Dexa and S-Power where the idea came from. The SMT was my idea as the PCB was quite tall initially, and the ground plane was my work too. I took the idea as far as that then we encountered the problem of the spacing between the mounting hole and bottom of the PCB causing a slight issue. Then Ant flipped the reg upside down and I tweaked it so that the traces were neater and all necessary vias were in place.
So I would say this as a definite team effort from Ant and I but the real credit must go the Teddy Pardo for coming up with the circuit in the first place
