W83310DG TR

Overview

The W83310DG TR is a bus termination regulator manufactured by Nuvoton Technology Corporation, designed for high-current applications. It operates within an input voltage range of 1.62V to 3.63V and provides a single output channel capable of delivering up to 2A. The device is housed in an 8-SOIC package with a width of 0.154 inches (3.90mm). It supports surface mount installation and functions within a standard operating temperature range of 0°C to 70°C.

Feature Summary

• Provides continuous bidirectional sinking and driving capability for DDR SDRAM bus terminator applications
• Integrates over-temperature and current limit protection mechanisms

Applications

• DDR SDRAM bus termination
• Intel Springdale GCH/MCH-VTT power regulation

Procurement Notes

Verify the specific suffix 'TR' indicates tape-and-reel packaging when sourcing. Confirm component status as discontinued or obsolete through official distributor channels prior to finalizing procurement plans. Ensure compatibility with existing board layouts regarding the 8-SOIC footprint and thermal requirements.

Selection Notes

Select this component for designs requiring robust bus termination with integrated protection features. Consider the 2A current capacity and SOIC package constraints against system power density needs. Verify that the 0°C to 70°C operating range aligns with the environmental conditions of the target application.

Part Context

This part belongs to the W83310 series of bus termination regulators from Nuvoton.
