[sdiy] Clean Power Supplies

[Glen]

I've been wondering, which voltage regulators have the least amount of noise? I
know we can discard most switch mode supplies, as being relatively high noise
devices. So then, which analog regulator would give the absolute least noise
for common audio circuitry like op-amps?

In addition to figuring out which regulator chip or circuit to use, one of my
gut feelings is to avoid regulator circuits with a potentiometer adjustment,
because the pot will eventually become a poor connection, and your supply
voltage will become noisy. Likewise, I would limit my use of mechanical
connectors, preferring to solder connections when possible.
