Can I power my ESP8266 with a L7806CV voltage regulator (6v, 1.5A) using the Vin pin of the board.
Which ESP8266 module do you have?
I have a LOL1n nodemcu board with an ESP-12E module.
Hi,
Please provide the board link.
The following:
Electrical Characteristics
The ESP8266's maximum voltage is 3.6V, so the Thing has an onboard 3.3V regulator to deliver a safe, consistent voltage to the IC. That means the ESP8266's I/O pins also run at 3.3V, you'll need to level shift any 5V signals running into the IC.
The input to this regulator can either be delivered by USB, LiPo battery, or through the VIN pin.
Max Input Voltage: If you supply power to the board through the VIN, make sure the voltage does not exceed 6V. That's the maximum input voltage of the AP2112K-3.3V regulator the board uses.
Alternatively, if you have an external, regulated, supply you'd like to deliver directly to the ESP8266, you can supply that voltage through the 3V3 pin (on the I2C header). While this voltage doesn't have to be 3.3V, it must be within the range of 1.7-3.6V.
So at 6.0 volts you are at the absolute maximum likely for your board. Your call as to what to do. Personally I would advise against it.

You need to look at the specification that comes with your particular board . I googled one that accepts 7-12 v on Vin, and looks like yours ( BUT CHECK).
Difficult to advise , except to read the documentation and stick within its limits .
The bare 8266 boards ( which you don’t have are 3.3v).
Note on the spec below 6v won’t work
