Richtek RT9045GSP

转换器，DDR 总线端接稳压器1V ~ 5.5V

Overview

The RT9045GSP 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 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 RT9045GSP 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 shutdown protection.
