Note 1:
External components such as the catch diode, inductor, input and output capacitors
can affect switching regulator system performance.
Note 2:
Output sourcing current. No diode, inductor or capacitor connected to output.
Note 3:
Feedback removed from output and connected to 0V.
Note 4:
Feedback removed from output and connected to 25V to force the output transistor OFF.
