#85163 Main snag with the HT7327 regulators is they are only specified to deliver 250mA output current. Although the average current of the esp8266 modules is typically less than 100mA, they can need up to 400mA for short periods of activity.

My personal preference is the XC6203 series which are specced to 400mA with short bursts to 600mA. Best to get the E variant without built in current limiter.

They are availbale at different output voltages including 2.7V if one wants to run at minimum voltage.
