I am in need of a way to attach a constant DC power source to a small cheap MP3 player (plugs into a phone system). I have all sorts of old DC power supplies around, but I need to get the voltage down to 1.5v for the MP3 player. Is there a simple circuit that I can put together to take a PS of, say, 4.8v / 350mA to the same voltage / current as a AAA battery?
Hope this make sense.
Thanks in advance... Todd
