I want to power my pic32 micrcontroller using a lead acid battery. I'm not the greatest with circuits (especially when it comes to power systems), but trying to learn. I have a 12v lead acid 10AH battery. I figured I could drop the voltage using a 7805 voltage regulator and plug that into my pic board. The thing that I am worried about is the output current of the battery. Would the battery only supply the current that is needed for my uC to operate or would I have to put some kind of current limiting circuit before my pic.
