Hello,
Like thousands before me I am moving from the life of batteries and wall-warts and onto the excitement of building my own variable bench supply. I am interested in the design process so I figured I could give this a try.
It seems as though the LM317 seems to be a common choice, but I have some discrete transistors and zeners lying around and would like to make use of them.
It seems as though discrete designs using only diodes and transistors (sometimes op-amps) are fairly complex and take up a fair amount of space on a schematic.
Might this be because the circuitry to get the output down to zero volts is that much more complex and also relies on temperature regulation as well, increasing the parts count?
