Figure 9: Output voltage response to step-change in load current (50%-75%-
50% of Iout(max); dI/dt = 0.1A/s). Load cap: 1uF ceramic and 10uF tanta-
lum capacitors. Top trace: Vout (500mV/div), Bottom trace: Iout (10A/div).
Figure 10: Output voltage response to step-change in load current (50%-
75%-50% of Iout(max): dI/dt = 5A/s). Load cap: 470F, 15 m
