ELECTRICAL CHARACTERISTICS CURVES
Figure 8: Output voltage response to step-change in load
current (75%-50% of Io, max; di/dt = 0.1A/µs). Load cap: 10µF,
tantalum capacitor and 1µF ceramic capacitor. Top Trace: Vout;
100mV/div; Bottom Trace: output current: 10A/div

Figure 10: Test set-up diagram showing measurement points
for Input Terminal Ripple Current and Input Reflected Ripple
Current.
Note: Measured input reflected-ripple current with a simulated
source Inductance (LTEST) of 12 µH. Capacitor Cs offset
possible battery impedance. Measure current as shown above.

current and nominal input voltage with 12µH source impedance
and 33µF electrolytic capacitor (200 mA/div 2us/div).
