7.3.3 Current Limit

This device features current-limit protection to keep the device in a safe operating area when an overload or output short-to-ground condition occurs. This feature protects the device from excessive power dissipation. For example, during a short-circuit condition on the output, the fault protection limits the current through the pass element to I(LIM) to protect the device from excessive power dissipation.
