RT9026 is a 3A sink/source tracking termination regulator. It is specifically designed for low-cost and low-external component count systems. The RT9026 possesses a high speed operating amplifier that provides fast load transient response and only requires 20μF of ceramic output capacitance. The RT9026 supports remote sensing functions and all features required to power the DDRI/II/III VTT bus termination according to the JEDEC specification. In addition, the RT9026 includes integrated sleep-state controls placing VTT in High-Z in S3 (suspend to RAM) and soft-off for VTT and VTTREF in S5 (shutdown). The RT9026 is available in the thermal efficient package SOP-8 (Exposed Pad), MSOP-10 (Exposed Pad) and WDFN-10L 3x3.
