May I ask what "regulated" means? I'm getting a feeling from this thread that it means that it stays steady at a certain voltage. But I'm thinking, if it is 5 volts, then how would it change? I'm seeing it has something to do with load, but I'm not quite getting it yet. Sorry if this is a dumb question, but is a battery regulated? (I realized that the battery goes down slowly over time. But we are talking seconds here I think, no?) Is this a similar problem to why those small wallwart sized 220 to 110v converters say that they cannot be used with electronic things? -----Original Message----- From: piclist-bounces@mit.edu [mailto:piclist-bounces@mit.edu] On Behalf Of Eric Jorgensen Sent: Wednesday, May 11, 2005 22:40 To: Microcontroller discussion list - Public. Subject: Re: [EE] Will phone charger work as a 5v DC power supply? It will work if it is a regulated 5V. Most wall warts that are regulated say so on the enclosure. If it doesn't say so, it probably isn't.
