Can I use it as a 5V regulator for a full circuit?

Not alone. At 0.5 W the current it can handle is limited. Use it with a series resistor for a small reference load, and add a transistor buffer or a dedicated regulator for higher currents.

Which end is the cathode?

The cathode is the end marked with the band. For voltage regulation, connect the cathode to the positive rail through a series resistor and the anode to ground.
