I'm just wondering. What is the basis for choosing, for example, an LM7805 over a mini DC-DC converter?
I see. So for my home projects thas has nothing to do with audio, the mini converter is the best choice?
3. breadboard space. Linear regulators are much smaller.
Only for less than one watt.
You didn't used to able to buy (or build) a mini switching dc/dc converter for a reasonable price...Even now, you can pretty much only get poorly-specified modules from somewhat questionable vendors smuggled past customs, which will be a problem for any "real manufacturer "...
