Source/Sink DDR Termination Regulator

RT9066

The RT9066 is a source/sink tracking termination regulator. It is specifically designed for low-cost and low-external component count systems. The RT9066 possesses a high speed operating amplifier that provides fast load transientresponse and only requires a minimum 30μF of ceramic output capacitance. The RT9066 supports remote sensing functions and all features required to power the DDRII / DDRIII and Low Power DDRIII / DDRIV VTT bus terminationaccording to the JEDEC specification. In addition, the RT9066 provides an open drain PGOOD signal to monitor the output regulation and an EN signal that can be used to discharge VTT during S3 (suspend to RAM) for DDR applications.The RT9066 is available in the thermal efficient package WDFN-16L 5x3.
