The 317 is a 'floating' regulator that has no reference to ground. What it regulates is the voltage between its output pin and the adjustment pin to 1.25V. The load voltage is determined by the load, not the regulator. The regulator limits the current through the load. Without load the output voltage equals the input voltage minus a small dropout voltage of about 1V. The minimum output current to maintain regulation is typ. 3.5mA but can be as high as 10mA (see pic). This is not predictable and must be measured.
