RT9199 Cost-Effective, 2A Peak Sink/Source Bus Termination Regulator General Description Features The RT9199 is a simple, cost-effective and high-speed Ideal for DDR-II VTT Applications linear regulator designed to generate termination voltage Sink and Source 2A Peak Current in double data rate (DDR) memory system to comply with Integrated Power MOSFETs the devices requirements. The regulator is capable of Generate Termination Voltage for DDR Memory actively sinking or sourcing up to 2A peak while regulating Interfaces an output voltage to within 20mV. The output termination High Accuracy Output Voltage at Full-Load voltage can be tightly regulated to track 1/2VDDQ by two Output Adjustment by Two External Resistors external voltage divider resistors or the desired output Low External Component Count voltage can be pro-grammed by externally forcing the Shutdown for Suspend to RAM (STR) Functionality REFEN pin voltage. with High-Impedance Output Current Limiting Protection The RT9199 also incorporates a high-speed differential On-Chip Thermal Protection amplifier to provide ultra-fast response in line/load transient. RoHS Compliant and 100% Lead (Pb)-Free Other features include extremely low initial offset voltage, excellent load regulation, current limiting in bi-directions and on-chip thermal shut-down protection. Applications Desktop PCs, Notebooks, and Workstations The RT9199 are available in both SOP-8 and SOP-8 Graphics Card Memory Termination (Exposed Pad) surface mount packages.
