Load switch, ET2016B, ETEK Microelectronics

The ET2016B is a current-limited P-channel MOSFET power switch designed for high-side load switching applications. This switch operates with input voltages ranging from 2.5 V to 5.5 V, making it ideal for both 3.3 V and 5 V systems. An integrated current-limiting circuit protects the input supply against large currents that may cause the supply to fall out of regulation. The ET2016B is also protected against thermal overload, limiting power dissipation and junction temperature. It can be used to control loads requiring 0.275 A to 2.7 A. The current limit threshold is programmed with a resistor from SET to ground. The quiescent supply current in active mode is only 25 μA, while in shutdown mode, the supply current decreases to less than 1 μA.
