RT9089A

DDR Termination Regulator

RT9089A
New

The RT9089A is a sink/source tracking termination regulator. It is specifically designed for low-cost and low-external component count systems. The RT9089A possesses a high speed operating amplifier that provides fast load transient response and only requires a minimum 10μF ceramic output capacitor. The RT9089A supports remote sensing functions and all features required to power the DDRI/DDRII/DDRIII/DDRIV/LPDDRII/LPDDRIII VTT bus termination according to the JEDEC specification. The RT9089A is available in the thermal efficient package, WDFN-10L 2x2.
