Protoboad power supply
I would like to run my protoboard in a car, so a max of 18V for a power supply, I am not using any extra periphials, so it really only needs the low current needed to power the Prop. Looking at the circuit and Nat Semi LM1086 specs it looks like it should not be a problem.
So I'd just like to confirm that is correct reasoning and de-rating to 6-9V 1.5A was for regulator heat sinking when running hight loads and/or the servo's?
At least at 12V I can afford a reverse polarity protection diode!

And they all put out up to 1amp out.. Works great for most projects.. I should also mention they are not just regulators... they are switching power supplies stuffed into a small 24pin IC.
Oh, and the best part is you can get free samples from the national website!
If you want to spend a bit more money, look into these:

(Do throw in bypass caps anyway, even if it says they're not necessary -- it almost never hurts, and a cap grab bag is cheap)
