Note 1: All currents into the device are positive; all currents out of the device are negative. All voltages are referenced to device
Note 2: ∆V
Note 3: This input current level is for the hot-swap enable (EN_, EN, EN) inputs and is present until the first transition only. After the
Note 4: Maximum current level applies to peak current just prior to foldback-current limiting. Minimum current level applies during
