I have a project that needs to pull power from an existing 6V system. I know 6V is shaky territory for Arduino boards because the regulator likes more than that and it's too much to put directly in. I probably won't be using a board anyway, I'll probably mount a 328 on a perf board.
But what are my best options for getting 5V out of 6V? LDO regulator? What's a good one?
