I'm a little new to electronics, and still don't quite understand the implications of making a few changes. In your circuit diagram for the Fixed Voltage Power Supply (http://www.aaroncake.net/circuits/supply6.asp), I'm want to try and get as an efficient conversion of power as possible. I only need 5v as this is used for a USB application. I'm looking at replacing the LM7805 with a R-785.0-1.0 (I dont need more than 1amp). I'm hoping to avoid a heatsink this way. I need some help in determining how this will effect the capacitors... Also, are there any other suggestions for increasing the efficiency? Many thank for the site.
