Voltage regulator circuit design
I'm trying to make a DC - DC voltage converter.
The real purpose is to power an old USB hub in a car. This is because so many of my electronics these days use USB to power them and rather than have a nasty mess of car power adapters I want to use a single 12V supply for the hub and then plug all of my goodies into it.
Now for the meat of the question.....
What is the best circuit design for using a voltage regulator. I have looked at some stuff in data-sheets and it just seems way too simple.
The part I'm looking at using is a National Semiconductor LM1085-5.0. Input voltage 6.5 - 20V output 5V max of 3A
