12V 5A power supply Regulator with LM1084IT-12

The basic car electrical system gives you around 12-13V when the engine is off and 13-14V when it is running. Not good for a computer, so the basic idea is to use a simple voltage regulator which takes an unregulated voltage in and outputs a regulated voltage. The LM1084IT-12 is a 12V, 5A, Low dropout voltage regulator in a TO220 package to which a heatsink will be added. The low dropout feature is nice as the cars supply varies so much.
