I have a project that needs a 3.3v regulator to run a esp-12e chip but needs 5v for the logic signal for an LED strip. My supply voltage is 12v. Is it better to drop the voltage to 5v and then wire the 3.3v regulator to that or run them both directly off the 12v supply. Which way would be better as far as dissipating the heat produced?
I have attached a picture of of both ways. Or is there a better way? Maybe a dual output regulator?
Thanks in advance for any advice!
