i was told "first step start with a zener" this is so i have a more stable circuit. so i usually start with a 12v zener, this is what i type into ebay or ask for at the parts store and this is what i get, a "12v zener". i never really questioned what i was getting till now. i was digging in my parts box and i came across a 1N5242B. when i looked up the data sheet it says it is an adjustable zener from 1v-200v. how can a regulated power device like a zener be adjustable?
also i have seen other power regulators usually in a TO-220 case are these adjustable too or are they "locked" like a zener?
any light shed on this would help me out a lot
