Note 1: No elements connected to output pin.
Note 2: Feedback pin removed from output and connected to 0V to force the output transistor switch ON.
Note 3: Feedback pin removed from output and connected to 12V for the 3.3V, 5V, and the A version, and
15V for the 12V version. To force the output transistor switch OFF.
