The Monolithic Power Systems MP5073GG-Z is a 2 A load switch for rails up to 5.5 V, supplied in a QFN package. It integrates a programmable current limit, a power-good indicator, slew rate control on the output, and an output discharge function. The pass element has 50 m Ohm of on-resistance. The device operates from -40 C to +125 C, is RoHS compliant, and is supplied on tape and reel.

An integrated load switch replaces a discrete MOSFET plus gate-drive and protection circuitry, controlling power to a downstream subsystem from a single logic enable. Slew rate control limits inrush current when a large bulk capacitance is charged, the programmable current limit protects against a shorted load, and output discharge ensures the rail collapses predictably at turn-off. Typical users include designers of smartphones and tablets, USB and accessory power paths, solid-state drives, set-top boxes, and industrial boards that power-sequence subsystems to reduce standby draw. The +125 C rating suits enclosed and automotive-adjacent placements.
