USB iPOD Charger based on REG1117A schematic

I think this subject will always get new project because of the spread of the ipods. People will always want to charge their iPods when their away or any mod to an iPod will always show interest for the public.

The circuit’s pretty simple, basicly it’s just a voltage regulator. Both the LM317 and the REG1117A (LDO) fit the PCB, maybe there are even more types that I’m aware of that can be used on it. I did add one extra thing: a LED that shows if the connected device is consuming power. To do this I used a shunt resistor and a current converter.
