Current Limited Switch

Description

The current limited P-channel MOSFET power switch designed for high-side load switching applications.
This switch operates with inputs ranging from 2.5V to 5.5V, making it ideal for both 3.3V and 5V systems. An integrated
current-limiting circuit protects the input supply against large currents which may cause the supply to fall out of regulation. The power switch is also protected from thermal overload which limits power dissipation and junction temperatures. 
The power switch is available in Pb-free packages and is specified over the -40°C to +85°C ambient temperature range.
