MP20073DH-LF

Overview

The MP20073DH-LF is a DDR memory termination regulator designed for DDR2 and DDR3 applications. It operates with an input voltage range of 1.3V to 6V and provides a regulated output current of 2A. The device features a buffered VTTREF output that is half of the reference voltage. It is housed in an MSOP-EP package and supports surface mount mounting. The component is rated for operating temperatures ranging from -40°C to 85°C or 125°C depending on specific variant documentation.

Feature Summary

• Provides regulated VTT output for DDR memory termination
• Includes buffered VTTREF output at half reference voltage
• Supports DDR2 and DDR3 memory standards

Applications

• DDR2 memory termination
• DDR3 memory termination
• System board power management

Procurement Notes

Verify the exact suffix (e.g., LF-P, LF-Z) against the required package type and temperature rating. Confirm that the MSOP-EP footprint matches the PCB design. Ensure the input voltage range aligns with the system's available power rails before procurement.

Selection Notes

Select this component when a dedicated 2A termination regulator is required for DDR2 or DDR3 buses. Consider the thermal performance of the MSOP-EP package for high-current applications. Verify compatibility with the system's reference voltage requirements for the VTTREF output.

Part Context

This part belongs to Monolithic Power Systems' specialized PMIC lineup for memory termination. It addresses the need for precise voltage regulation in high-speed memory interfaces. The device simplifies board design by integrating the termination regulator and reference buffer into a single compact package.
