MP20075DH-LF

Overview

The MP20075DH-LF is a precision DDR2/3/3L/4 termination low-dropout (LDO) regulator designed to provide accurate VREF/2 tracking voltage for memory termination. It delivers up to 3A of source/sink current with ±30mV output accuracy. The device supports Kelvin sampling via the VTTSEN pin and requires only 20μF of ceramic output capacitance for stable transient response. Operating within a VDDQ range of 1.05V to 3.6V, it features built-in soft start, under-voltage lockout, over-current limit, and thermal shutdown protection in an 8-pin MSOP package.

Feature Summary

• Provides precise VREF/2 tracking voltage for DDR2, DDR3, DDR3L, and DDR4 memory termination applications
• Supports Kelvin sampling functionality for improved output voltage regulation accuracy
• Integrates comprehensive protection mechanisms including soft start, UVLO, OCL, and thermal shutdown

Applications

• DDR2 memory system termination
• DDR3 memory system termination
• DDR3L memory system termination
• DDR4 memory system termination

Procurement Notes

Verify the specific suffix variant against official MPS documentation to confirm exact electrical characteristics and packaging options. Confirm lead times and availability status directly with authorized distributors as supply conditions may vary. Ensure compatibility with target VDDQ voltage ranges and thermal requirements before integration.

Selection Notes

Select this component when designing systems requiring high-precision VTT regulation for DDR2 through DDR4 interfaces. The integrated Kelvin sensing capability addresses trace resistance errors, while the low output capacitance requirement simplifies board layout. Evaluate thermal dissipation capabilities based on the 3A current rating and operating ambient temperature constraints.

Part Context

This part belongs to the MP200 series of power management ICs from Monolithic Power Systems. It serves as a specialized solution for memory termination, distinct from general-purpose LDOs or switching regulators. The device complements other PMIC offerings by addressing the specific dynamic load and accuracy demands of modern high-speed memory buses.

Replacement Considerations

Public confirmed substitute part numbers include MP20075DH-LF-P and MP20075DH.
