RT9026
DDR Termination Regulator
General Description
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
and low-power DDRIII/DDRIV 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.
