so learning about circuits etc and I need 3.3 to power my esp-01 to control a relay.
using a lm317 regulator i have built the circuit. I am using a 220uf to bridge vin to ground.
my vin is 13.2v at 1.2a. what voltage should the cap be? i would assume 220uf 16v would be fine?
the second cap is 10uf and that bridges vout (3.3) to ground. would a 10v cap work there?
would i be better using say a 36v cap on both?
yes i know i could go out and buy a buck converter but thats not going to teach me anything
