Over-Current Response with Ramped Load
on OUT1 and Fixed Load on OUT2 (Note 10)
Inrush Current to Downstream Device

Note 10: Output is shorted to Ground through a 100 mΩ resistor.
Note 11: Load is two capacitors and one resistor in parallel to model an actual USB load condition. The first capacitor has a value of 33 µF to model the LM3544
output capacitor. The second capacitor has a value of 10 µF to model the maximum allowable input capacitance of the downstream device. The resistor is a 47Ω
resistor to model the maximum allowable input resistance of the downstream device.
