Esp8266 feather smoked regulator

Post by gordonendersby »

Hi,

In my hurry to play with my new esp8266 feather I assumed that the lipo i plugged in was the correct polarity.
It wasnt. There doesnt seem to be any polarity protection on the feather.

Smoke came from the a 5 pin chip, that I assume is a regulator, next to the usb controller.
Ive got a nice pin prick burn on my thumb.
I pulled the plug immediately so looks like damage was just my thumb and the regulator.

Could you tell me the specs of the regulator so i can replace it please.

Thanks

Gordon

Theres another similar package on board that is the charge controller.
Ive looked at the eagle files but cant work out whether whats blown is the regulator or the charge controller.
Cant work out in the board file from the positions as the component labels seem to be missing.
I think its the regulator but would like to confirm that it is.

There are two 5-pin chips. The one closest to the BAT and EN pins is the regulator. The other one is the charge controller.

The charge controller is here:
