NCT3107S TR

Overview

The NCT3107S TR is a DDR-SDRAM bus termination regulator manufactured by Nuvoton Technology Corporation. It functions as a switching voltage regulator designed to provide stable power termination for DDR memory interfaces. The device incorporates short-circuit protection mechanisms and includes an enable control pin for system power management. It features a remote sense voltage pin (VSEN) to ensure accurate load regulation under varying conditions. Additionally, the component provides a reference voltage output (VREF) and supports a suspend mode to reduce power consumption during memory inactivity.

Feature Summary

• Integrated short-circuit protection for enhanced circuit reliability
• Remote sense voltage capability for precise load regulation
• Dedicated enable control pin for system power management
• Reference voltage output and memory suspend functionality

Applications

• DDR-SDRAM bus termination circuits
• Memory subsystem power regulation
• Embedded systems requiring low-power memory states

Procurement Notes

Verify the specific suffix 'TR' indicates the tape-and-reel packaging configuration when ordering. Confirm that the component meets RoHS and green manufacturing standards required by your supply chain. Ensure the manufacturer designation matches Nuvoton Technology Corporation to avoid counterfeit parts. Cross-reference the Mouser part number 503-nct3103str if verifying against distributor databases, noting potential data entry variations in public listings.

Selection Notes

Select this component when designing DDR memory interfaces requiring dedicated termination regulation rather than discrete resistor networks. The inclusion of remote sensing makes it suitable for layouts where voltage drop compensation is critical. Consider the enable control feature if system-level power sequencing or standby modes are required. Verify compatibility with the specific DDR generation supported by the VSEN and VREF outputs.

Part Context

This component belongs to the NuMicro PMIC family from Nuvoton, specifically categorized under switching voltage regulators. It addresses the power integrity needs of high-speed memory buses. The product falls within the broader category of power management ICs used in embedded computing and consumer electronics. Its design focuses on integrating termination regulation with protection features to simplify board layout.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate alternative DDR termination regulators only after verifying electrical compatibility with the VSEN and VREF specifications.
