Description
The RT9172-18PG is a low-dropout linear regulator in the RT9172 series. It operates from a +2.25V to +6.0V input supply and is suitable for low voltage microprocessor applications. The regulator features a fast response to step changes in load, an internal PMOS pass device to avoid extra GND current in heavy load and dropout conditions, and a low operation current shutdown mode for power-saving systems. It also includes current limiting and over temperature protection.
