2533705

a while ago i made an esp8266 circuit to power cycle my modem as part of an automatic ban evasion script. it was a perfboard nigger rig and the poor little sot223 3v3 linear regulator finally died. i'm redoing the circuit now with a switcher so it won't burn up in its sealed enclosure.
QUESTION: has anyone run an ESP off a switcher? how sensitive is it to supply ripple? i added pads for an optional linear postregulator and shield can but i'd rather not bother with those.

it's listed for each capacitor model individually on their search tool, along with the other useful info like dc bias derating
