Figure 5: Output voltage response to step-change in load current (50%-75%-
50% of Iout(max); dI/dt = 0.1 A/µs). Load cap: 1 µF ceramic and 15 µF tantalum
capacitors. Ch 1: Vout (1V/div), Ch 2: Iout (5A/div).
Figure 6: Output voltage response to step-change in input voltage
(250 V/ms). Load cap: 100 µF, electrolytic output capacitance. Ch 1: Vout
(1V/div), Ch 2: Vin (20V/div).
