RT9026GSP

Overview

The RT9026GSP is a DDR bus termination regulator manufactured by Richtek USA Inc., designed for low-cost systems with minimal external components. It features a high-speed operational amplifier for fast load transient response, requiring only 20µF of ceramic output capacitance. The device supports remote sensing and provides integrated sleep-state controls for S3 suspend-to-RAM and S5 shutdown modes. It operates within an input voltage range of 3.15V to 5.5V and functions across a temperature range of -40°C to 85°C. Packaged in an 8-SOP-EP (Exposed Pad) surface-mount configuration, it complies with JEDEC specifications for DDRI/II/III and low-power DDRIII/DDRIV VTT bus termination.
