2: No diode, inductor or capacitor connected to output pin.
3: Feedback pin removed from output and connected to 0V to force the output transistor switch ON.
4: Feedback pin removed from output and connected to 12V for the 2.5V 3.3V, 5V, and the ADJ. version, and
5: V
Absolute maximum ratings are stress ratings only and functional device operation is not implied.
