Cost-Effective, 2A Peak Sink/Source Bus Termination Regulator
General Description
The RT9199 is a simple, cost-effective and high-speed linear regulator designed to generate termination voltage in Double Data Rate (DDR) memory system to ply with the devices requirements. The regulator is capable of actively sinking or sourcing up to peak 2A for DDRII or 1.5A for DDRIII 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...
