AP2303 DDR LDO Regulator

Diodes Incorporated AP2303 DDR LDO Regulator is a low dropout linear regulators to generate termination voltage of DDR-SDRAM systems. 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. 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. The AP2303 features over temperature protection and current limit protection for both source and sink. AP2303 is available in packages of SOIC-8 and PSOP-8.
