I am looking to get a constant, clean 12v from my cars 12v line. I am wondering if all I am in need of to pull this off would be a simple 12v fixed regulator?
The 12v would be hooked up to a pico motherboard (19v max input), 7" lcd monitor and an arduino.
I did find this schematic here: **broken link removed**
So would a simple regulator be good or not? Will it need a heat sink?
The posted circuit is crap; created by an inexperienced novice.
Sim shows V(out) on the Y-axis vs V(in) on the X-axis at load currents of 20, 40, 80, 160, and 320mA. Note that it does a crummy job of holding the voltage constant, and it only works (poorly) for load currents less than 50mA. Why the 5A fuse is there is beyond me...
The NUC is rated from 12v-19v. Not sure of the wattage but the old ones are rated at 65w and i have no idea how many amps. The LCD and arduino... well i really have no idea right now. Maybe 0.50amps for the LCD and less for that on the Ardunio.

Unless you need it to work while cranking the starter, you do not need a step-up converter with all of its complexity. Follow the link in my previous posting to get an automotive LDO that requires maybe two external capacitors.
It's for the PICO PC why not just supply the cars raw DC to the PICO since it's rated for 19V (it must have a DC/DC converter)? They do sell PICO PCs for cars with all the power supply dodads already done. You could power your Arduino off the PS/2 or USB port. Not sure why you need a full blown PC in a car. You'll also have to power the HDD. How about an Android box, Beagle board or Raspberry Pi (they have video)
What's this thing for? A backup camera (cheaper just to buy one).
PS PC operating systems aren't keen on being shut off, they do like being shut down.
Yes it will have proper air flow. And yes I will be using an ssd. i3 or i5 will be fine. Yes its a little overkill but its still less than a windows tablet with 80% better specs.
