design.

Note 3: All currents into the device are positive. All currents out of the device are negative. All voltages are referenced to device

ground, unless otherwise noted.

Note 4:

Note 5: The short-circuit output current is the peak current just prior to current limiting; the short-circuit foldback output current

applies during current limiting to allow a recovery from bus contention.
