/diy/ - Do It Yourself

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.
