Preliminary Datasheet

2A DDR TERMINATION REGULATOR

AP2302L

General Description

Features

Support Both DDR I (1.25V ) and DDR II

The AP2302L 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 2A current continuously, providing

enough current for most DDR applications. Output

voltage is designed to track the reference voltage

within a ± 20mV 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 2A

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 AP2302L, used in conjunction with series termi-

nation resistors, provides an excellent voltage source

for active termination schemes of high speed transmis-

sion lines as those seen in high speed memory buses

and distributed backplane designs.
