Hi, I'm new here so bear with me. I have some experience with electronics and circuit design, but it's been awhile. Here is my situation. I have a motorhome and I want to convert my 12 volt incandescent lights to leds. I put in some led boards and they kept overheating and burning out. It appears that my supply voltage varies too much. When my solar panel is charging my batteries, I have 13.5 volts. I beleive that is what is overheating my led boards. Putting in a 7812 12 voltage regulator won't work because they have a drop out voltage of 1.5 - 2 volts. I don't always have the 13.5 volts. I need something that will limit the output to a maximum of 12 volts. If the input voltage falls below 12, the output will follow it down. If the input voltage goes above 12, the device will limit the output to 12 volts. Any suggestions are appreciated. Thanks.
