Just to clarify: voltage regulators can only *decrease* voltage. They serve to ensure a steady supply from a source slightly higher than what you want, and help filter out noise in the power supply. They can't do a damn thing about the source voltage dropping too low. -- Paul Winkler home: http://www.slinkp.com "Muppet Labs, where the future is made - today!"
