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.

Key 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.
