I have a circuit that outputs 3v-17v for an enable pin. However, I need to limit this to be no more than 5V for many applications (but 2V-5V is fine). My preferred output is around 3v or so. I was thinking of putting 5 diodes together (5*0.65v = 3.25V -- but even 4 diodes which gives 2.6v should be fine). Otherwise, I would use a regulator. It's only about 40ma of current or so. This seems like the "easy way" to do it (I know there are other ways). My question: which way is better? which way is cheaper?
Thanks!
Thanks!
