RT9173APM5 Description

Short technical summary and product information.

The RICHTEK RT9173APM5 is a specialized voltage regulator designed for DDR memory termination applications. It is capable of sourcing and sinking up to 3A of peak current, making it suitable for active termination schemes in high-speed transmission lines.

 

This regulator supports both DDR 1 (1.25VTT) and DDR 2 (0.9VTT) requirements, offering flexibility for different memory standards. The output voltage is adjustable via external resistors, allowing for precise voltage setting. It operates within a voltage supply range of 1.6V to 6V and features integrated power MOSFETs for efficiency.

 

The RT9173APM5 is available in a TO-263-5 package, a surface-mount type suitable for various PCB designs. It includes essential protection features such as current-limiting and thermal protection, enhancing its reliability in demanding applications. The device also supports a shutdown mode for standby operations.

 

This component is RoHS compliant and 100% lead (Pb)-free, aligning with modern environmental standards for electronic components.
