adjustable voltage regulator help

[gezzuzz]

im looking for a adjustable voltage regulator

input would be 12v from a car battery so it may range from 10-14v

would have to be adjustable output with min ranges 4.5v-0.5v

easy to turn knob that you can turn with you fingers would be nice too

i don't know how to look for parts like this im a programmer not a engineer.

thanks in advance

How much current?

 

[gezzuzz]

no more then 10A

no more then 10A

That's an EXTREMELY high current as far as electronics go, making it much more complicated, expensive, and probably large.

What is needed for?.

The lm338k is 8 amp and the ips338av is the same except it is in a TO-3 case. They are both real nice. I usually just use the lm317t, but it is only 1.5 amps and you say you want 10 (which is hard to believe).
