Description
The is a simple, cost-effective and high-speed linear regulator designed to generate termination voltage in double data rate (DDR) memory system to comply with the devices requirements. The regulator is capable of actively sinking or sourcing to 2A peak while regulating an output voltage to within 20mV. The output termination voltage can be tightly regulated to track 1/2VDDQ by two external voltage divider resistors or the desired output voltage can be pro-grammed by externally forcing the REFEN pin voltage. The RT9199 also incorporates a high-speed differential amplifier to provide ultra-fast response in line/load transient. Other features include extremely low initial offset voltage, excellent load regulation, current limiting in bi-directions and on-chip thermal shut-down protection. The RT9199 are available in both SOP-8 and SOP-8 (Exposed Pad) surface mount packages.
