Am I the only person who gets really nitty-gritty about component selection? Well probably not, but I am having a bit of trouble picking out my power management ICs. I am building a dual rail power supply. I guess you could call it that. It can do +/-12V and +/- 5V. It may be useful somewhere down the line. So, the most I have every really done in electronics is a AA battery source, a cap, resistor, and maybe an LED or lightbulb. I am looking to change my ways here. But regarding the ICs. I need a 7812, 7912, 7805, and 7905. Here's a link to what I am talking about: http://www.mouser.com/Semiconductors/Power-Management-ICs/Linear-Regulators-Standard/_/N-5cg9g?P=1z0w8gzZ1yzvdtq&Keyword=7812&FS=True [Broken] Note Line Regulation and Load Regulation. I didn't know either were measured in such a matter. I thought it was a percent or fraction or something. In this case, would it be better to go for one with a higher or lower Load/Line Regulation for a more stable supply? Thanks.
