DDR BUS TERMINATION REGULATOR

Description

Pin Assignments

The AP2303 is a low dropout linear regulator to generate termination

voltage of DDR-SDRAM system. The regulator can source or sink up

to 1.75A current continuously. The output voltage is regulated to track

tightly with the reference voltage (1/2V_DDQ) within ±10mV.

GND

The AP2303 supports soft start-up when used to turn on the VCNTL

and VREFEN. It integrates a shutdown circuit that will be triggered

once the voltage of VIN, VCNTL or VREFEN falls below a certain

value.

AP2303 features over temperature protection and current limit

protection for both source and sink.

SOIC-8

AP2303 is available in packages of SOIC-8 and PSOP-8.
