Transient Response Waveforms

Vout=3.3 V, 50% to 75% Load Transients

Vout=3.3 V, 75% to 50% Load Transients

Vout=5.0 V, 50% to 75% Load Transients

Vout=5.0 V, 75% to 50% Load Transients

Note: Transient Response is tested at di/dt=0.1 A/us (Vo=3.3 V), di/dt=0.5 A/us (Vo=5.0 V), Vin=48 V, Ta=25°C,

with a 1 µF ceramic capacitor and a 10 µF tantalum capacitor at the output.
