Description

The LP25151T5-A are 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

is also protected from thermal overload which limits power dissipation and junction

temperatures. Current limit threshold is fixed internally. The quiescent supply current in active mode is only 25

μA. In

shutdown mode, the supply current decreases to less than 1

μA.
