Figure 5: Output voltage response to step-change in load current (50%-75%-
50% of Iout(max); dI/dt = 0.02 A/µs). Load cap: 1 µF ceramic capacitor. Ch 1:
Vout (5 V/div), Ch 2: Iout (1 A/div).
Figure 6: Output voltage response to step-change in input voltage
(1000 V/ms). Load cap: 100 µF, electrolytic output capacitance. Ch 1: Vout
(500 mV/div), Ch 2: Vin (50 V/div).
