- Tue May 12, 2020 6:50 am #87059 The MCP1700 is a nice regulator but it can only supply 250mA output current which is not really enough for ESP8266 applications as the chip can draw 350mA for short periods. A large reservoir capacitor on the output would help suuplly during peaks.

The XC6203E can supply 400mA (peaks up to 600mA) and has a fairly low quiescent (8uA typ, 16uA max).
