A Product Line of Diodes Incorporated AP2303 DDR BUS TERMINATION REGULATOR Description Pin Assignments NEW PRODUCT 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 (1/2VDDQ) within ±10mV. (Top View) 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.
