ESP8266-12E not powering up

Hello everyone,

I have just started small development on ESP8266 WiFi module, so I got the module and breakout board as well.
Now as per the datasheet I'm trying to power the module with 3.3V but the module did't work. So I started to troubleshoot the issue and found that Voltage at Vcc is dropped to 1.7V-2.2V. Here the sources for the module which I tried :

  • Laptop USB connected to a 3.3V regulator
  • Arduino 3.3V
  • Adaptor which source 5V

in the all the cases the voltages are dropping. Troubleshooting further I found that the module is drawing 50-60mA of current. The only source remaining is a Li-Ion battery and 5V( which is not recommended but the system has safety as mentioned on Pg-17/31 of the datasheet:File Not Found

Looking for suggestion and troubleshooting methods or mistakes I'm doing in the setting up the module.

Regards,
