I've been using a 5.1 v regulator both to power an Arduino and provide current for off-board passive components in a project.
I'm beginning to wonder, though, whether the Arduino's regulator might be capable of supplying my off-board needs as well. I could eliminate that off-board regulator.
I can't find specs for max current/power drain on that regulator -- can't even find out quite what that chip IS.
Anyone know? I hate to blow one up finding out the hard way. ;-)
