This device is made by Panasonic and the various voltage versions seem to be rated at 2A max output current. The main difference between the AN78xx and the AN78xxF is that the F version package only has a maximum power dissipation of 10.25W compared to 15W for the non-F version.
I have seen that on PCBs of Fanuc CNC Power Supply, Spindle/Servo Amplifiers they only use AN78xxF regulators. It also seems that this type of regulator is, also, extremely stable at operation, producing very little noise/ripple.
