Update Alert Share

The RT9088B is a sink/source tracking termination regulator. It is specifically designed for low-cost and low-external component count systems. The RT9088B possesses a high speed operating amplifier that provides fast load transient response and only requires a minimum 30μF ceramic output capacitor. The RT9088B supports remote sensing functions and all features required to power the DDRIII and Low Power DDRIII / DDRIV VTT bus termination according to the JEDEC specification. In addition, the RT9088B 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 RT9088B is available in the thermal efficient package, WDFN-10L 2x2.
