Id like to make a simple 5v power adaptor plug so i can charge a cell ph from any rc car battery such as a 2s lipo battery.
ideally id like it all to solder up so i have a usb port and XT60 connector with the regulator all resin'd into one compact hard case adaptor...
whats a suitable 5v regulator chip that can handle say 3 amps plus so it will carry the required current without extra transistors etc?
