RT9173GS

Overview

The RT9173GS is a linear regulator IC from Richtek USA Inc., designed for DDR bus termination applications. It operates with an input voltage range of 1.7V to 6V and provides a single adjustable output. The device is housed in an 8-SOP package and supports surface mount installation.

Feature Summary

• Designed specifically for generating termination voltages in double data rate (DDR) memory systems.
• Utilizes a simple, cost-effective linear regulation architecture for high-speed performance.

Applications

• DDR bus termination voltage generation
• Memory module power management

Procurement Notes

Verify the specific suffix 'GS' against the manufacturer's official datasheet to confirm pinout compatibility and thermal characteristics. Ensure the component meets RoHS standards if required by your assembly process. Cross-reference the part number with authorized distributors to confirm current availability status and authenticity before procurement.

Selection Notes

Select this component when designing DDR memory interfaces requiring precise termination voltage control. Consider the 1.7V to 6V input range and adjustable output capability. Evaluate the 8-SOP package constraints for PCB layout and thermal dissipation requirements relative to the expected load current.

Part Context

This part belongs to the RT9173 family of special purpose regulators. Variants such as RT9173B and RT9173D share similar functional goals but may differ in specific electrical parameters or packaging options. The GS suffix typically denotes a specific package type and tape/reel configuration within the product line.

Replacement Considerations

Check for direct substitutes like RT9173B or RT9173D, ensuring pin compatibility and electrical specifications match the design requirements. Verify that any replacement maintains the necessary input/output voltage ranges and package dimensions for the existing footprint.
