RTQ2508

DDR Termination Regulator

General Description

Features

^VIN Input Voltage Range : 1.1V to 3.5V

^VCNTL Input Voltage Range : 2.9V to 5.5V

^Support Ceramic Capacitors

^Power Good Indicator

The RTQ2508 is a sink/source tracking termination

regulator. It is specifically designed for low-cost and low-

external component count systems. The RTQ2508

possesses a high speed operating amplifier that provides

fast load transient response and only requires a minimum

10μF x 3 ceramic output capacitor. The RTQ2508 supports

remote sensing functions and all features required to power

the DDRIII and Low Power DDRIII / DDRIV VTT bus

termination according to the JEDEC specification. In

addition, the RTQ2508 provides an open-drain PGOOD

signal to monitor the output regulation and an EN signal

that can be used to discharge VTT during S3 (suspend to

RAM) for DDR applications.

^10mA Source/Sink Reference Output

^Meet DDRI, DDRII JEDEC Spec

^Support DDRI, DDRII, DDRIII and Low Power DDRIII/

DDRIV VTT Applications

^Soft-Start Function

^UVLO and OCP Protection

^Thermal Shutdown

Applications

 Notebook/Desktop/Server

The RTQ2508 is available in the thermal efficient package,

WDFN-10L 3x3.

 Telecom/Datacom, GSM Base Station, LCD-TV/PDP-

TV, Copier/Printer, Set-Top Box
