OK... Did you try it with the regulator in, but no LED? <--- try this.
Active high means it turns on when voltage is + for the control pin, and off low means that the pin is in ground state to shut it off.
Surprised you got 4 volts with no regulator. This is at the atty connector?????
the 470 ohm resistor goes between the ctrl pin and ground.
