Nokia N8-00 Camra Not warking ways

By simple inspection, found that there is no supply voltage of 1.8 volts camera. Responsible for it marked on the stabilizer circuit phone Nokia N8 as N1515 , unfortunately without any labeling. First I would like to power the camera from the voltage VIO is also 1.8 volts, the camera certainly earned after I gave food, but the phone went to reboot after a few seconds the camera.
