Preliminary Datasheet

1.5A DDR TERMINATION REGULATOR

AP2301

General Description

Features

Support Both DDR I (1.25V ) and DDR II

The AP2301 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 1.5A current continuously, offers enough

current for most DDR applications. Output voltage is

designed to track the reference voltage within a 2%

tolerance for load regulation while preventing shooting

through on the output stage. On-chip thermal limiting

provides protection against a combination of high cur-

rent and ambient temperature which would create an

excessive junction temperature.

(0.9V ) Requirements

Source and Sink Current up to 1.5A

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 AP2301, 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.

The AP2301 is available in SOIC-8 and TO-252-5L

packages.
