Preliminary Datasheet

3A DDR TERMINATION REGULATOR

AP2302

General Description

Features

Support Both DDR I (1.25V ) and DDR II

The AP2302 linear regulator is designed to meet the

JEDEC specification SSTL-2 and SSTL-18 for termi-

nation of DDR-SDRAM. The regulator can sink or

source up to 3A current continuously, offers enough

current for most DDR applications. Output voltage is

designed to track the reference voltage within a 2%

(DDR I) and 3% (DDR II) tolerance for load regulation

while preventing shooting through on the output stage.

On-chip thermal limiting provides protection against a

combination of high current and ambient temperature

which would create an excessive junction temperature.

(0.9V ) Requirements

Source and Sink Current up to 3A

High Accuracy Output Voltage at Full-load

Adjustable V

by External Resistors

OUT

Shutdown for Standby or Suspend Mode

Operation with High-impedance Output

Applications

The AP2302, used in conjunction with series termina-

tion resistors, provides an excellent voltage source for

active termination schemes of high speed transmission

lines as those seen in high speed memory buses and

distributed backplane designs.
