And YES, those switching regulators WASTE .5W as heat as they are not 100% efficient, 90%-92% at best.
I am laughing at YOUR statement, its pretty darn funny when folks think they know electronics..
Thanks for the comic relief, I needed that after dealing with stupid wet behind the ears engineers that make twice the money that I make, fixing their stupidity..
