Cost-Effective, 1.8A Sink/Source Bus Termination Regulator
General Description
The RT9045A 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 1.8A while regulating an output voltage to within 20mV. The output termination voltage can be tightly regulated to track VDDQ / 2 by two external voltage divider resistors or the desired output voltage can be programmed by externally forcing the REFEN pin voltage.
The RT9045A also incorporates a high-speed differential amplifier to provide...
