    The schematic looks OK and identical to the one in the datasheet. Please double-check if pin 2 (SENSE) is really connected to pin 1 (OUT).

    If all pins are connected correctly, there is only a possible defect in the component, since the control transistor is fully turned on if the output shows 4.7V.
