What is the difference of regulator AN78xxF to the typical 1A regulators?
Where can i download it's datasheet?

THNX

RE: Voltage Regulator

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 viewed the data sheet at www.freetradzone.com - but you have to register. You shpuld be able to get it directly from the Matsushita/Panasonic site.

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.
