RT9045GSP Description

Short technical summary and product information.

The RICHTEK RT9045GSP is a specialized linear regulator designed to generate termination voltage for DDR memory systems, ensuring compliance with device requirements. It is capable of sinking or sourcing up to 1.8A, with specific ratings for DDRII, DDRIII, LPDDRIII, and DDRIV interfaces.

 

This regulator features integrated power MOSFETs and is stable with output ceramic capacitors. It offers high accuracy output voltage at full load, with an output voltage tolerance of within 20mV. The output voltage can be adjusted using two external resistors or programmed by forcing the REFEN pin voltage. Other features include current limiting protection in both directions and on-chip thermal shutdown protection.

 

The RT9045GSP is ideal for applications such as desktop PCs, notebooks, workstations, and graphics card memory termination. It is supplied in an 8-SOP-EP package and is suitable for surface mount applications. The operating temperature range is -40°C to 85°C, and it operates within a voltage range of 1V to 5.5V.
