RT9026GFP

Overview

The RT9026GFP is a 3A sink/source tracking termination regulator 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 powers DDRI/II/III and low-power DDRIII/DDRIV VTT bus termination per JEDEC specifications. Integrated sleep-state controls place VTT in High-Z during S3 suspend-to-RAM and provide soft-off for VTT and VTTREF in S5 shutdown states.

Feature Summary

Provides 3A sink/source tracking regulation for memory bus termination
Supports remote sensing functions for improved voltage accuracy
Integrates sleep-state controls for S3 suspend and S5 shutdown management

Applications

DDRI/II/III Memory Termination
Low-Power DDRIII/DDRIV Memory Termination
SSTL-2 and SSTL-18 Termination
HSTL Termination

Procurement Notes

Verify the specific suffix 'GFP' against official Richtek documentation to confirm package type and tape/reel configuration. Ensure compatibility with required thermal performance and pinout requirements for the target PCB layout. Cross-reference ordering information to confirm current availability status and manufacturing origin details.

Selection Notes

Select this component for applications requiring precise VTT tracking with minimal external capacitance. Consider the exposed pad packages for enhanced thermal efficiency. Verify that the input voltage range and operating temperature limits align with the system's power supply architecture and environmental constraints.

Part Context

The RT9026 belongs to Richtek's DDR termination regulator family, addressing power management needs for synchronous DRAM interfaces. It complements other PMIC solutions by providing dedicated, high-current termination capabilities essential for maintaining signal integrity in high-speed memory buses across various computing platforms.
