ELECTRICAL CHARACTERISTICS CURVES

Figure 5: Output voltage response to step-change in load

current (75-50% Iomax; di/dt = 1A/µs). Load cap: 10µF

tantalum capacitor and 1µF ceramic capacitor. Top Trace: Vout

(0.2V/div, 200us/div), Bottom Trace: Iout (1A/div). Scope

measurement should be made using a BNC cable (length

shorter than 20 inches). Position the load between 51 mm to

76 mm (2 inches to 3 inches) from the module

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. Measured current as shown

below
