    That one is the 2amp output and just a plain old regulator. It will need caps on both sides of + feeds on in and output and 1 connection is for turning it on or off. The other unit I showed you has the caps built on the little circuit board but is only 1.5amp output and no on/off pin. SNO

    Looks like 0.33uF cap on input side and 47uF on output side

    cool, do I wire them from the chip negative to the screen positive , and negative to the chip on the input to positive to the battery? Also these are plastic, so i take it there is no need for a heat sync?

    No need for heat sink since you are only dropping alittle bit. you could feed 12v+ from ignition on and it will turn on the regulator and monitor or feed pin 4 12v+ from battery and it will always be powered. SNOName:  12vregulator.jpg

    The caps should always be at least a 1/3rd higher in voltage rating (my opinion only) I personally would like to see a 16v cap on output side and a 25v cap on input side. They are really just to smooth out the current flow. You could go with larger size uF wthout much problem, just not under size. SNO

    By the way if anyone is looking for the 3 prong 12 v.220 chips already on a massive heat sync, just disassemble a old atx power supply for a PC. I found 4 of them hooked up to a heat sync. And m not sure but I think the other heat sync had the 5 v ones...
