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