GENERAL DESCRIPTION
The
between 1.65 V and 6.5 V that is protected against reverse
current flow from output to input. A load switch provides power
domain isolation, thereby helping to keep subsystems isolated and
powered independently and enabling reduced power consumption.
The
that supports more than 1 A of continuous load current. The
low 2.5 μA quiescent current and ultralow shutdown current
make the
