AP2303 - DDR BUS TERMINATION REGULATOR

General Description

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.

Key Features

  • over temperature protection and current limit protection for both source and sink. The AP2303 is available in packages of SOIC-8 and PSOP-8. Features.
  • Support DDR-II (VTT = 0.9V), DDR-III (VTT = 0.75V), DDR-IIIL (VTT = 0.675V), DDR-IV (VTT = 0.6V).

OR Description 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. 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. The AP2303 is available in packages of SOIC-
