Figure 25: Maximum Startup Load Current versus Load Capacitance.
Derate the load during startup according to this figure to avoid the pos-
sibility of over-current shutdown.

0.9Vo unit attempts to turn on into a 10 mΩ short circuit. Top trace
(100µs/div) is an expansion of the on-time portion of the bottom trace.
