[arm-allstar] Cleanest 13.6v to 5 volt conversion

[Josh Hatton]

Hey David Thanks again -
I've read chatter where some audiophiles are running these very units at
7-8VDC, then following that with a 7805 regulator/stack of regulators.  I
assume you've had no noise/whine issues out of these?

I am trying to keep a Pi going that would flop over to battery backup if
commercial power fails... If it's not a constant voltage (dwindling down
over hours), would they pose a problem?

Just talking through the scenario.
