8.2.3 Application Curves

Figure 36 shows a an example of initial inrush or short-circuit current limit. Test conditions: EN is from low to high, load is resistive short-to-GND or with a 470-µF capacitive load, external current limit is 2 A. CH1 is the output current. CH3 is the EN step.

Figure 37 shows an example of current limit during hard short-circuit. Test conditions: EN is high, load is (5 µH + 100 mΩ), external current limit is 1 A. A short to GND suddenly happens.
