Package Style:  SC-74A (TSOP-5, SOT-25)
Mounting Method: Surface Mount
Features & Applications
The NCP380HSN05AAT1G is a fixed current- limiting power-distribution switch; available in TSOP-5 package.

This device includes an integrated 55 mA (DFN package), P−channel MOSFET. The device limits the output current to a desired level by switching into a constant−current regulation mode when the output load exceeds the current−limit threshold or a short is present.
