How do I connect it as a voltage regulator?
Connect the cathode (marked with a band) to the positive supply and the anode to ground through a series resistor. The output is taken across the diode in reverse breakdown.
How do I choose the series resistor?
Use R = (Vin − Vz) / (Iz + Iload), where Vz is the zener voltage, Vin is the supply voltage, Iz is the desired zener current and Iload is the load current. Check that the resistor power and the diode power rating are not exceeded.
