The AP1127 is a low cost linear regulator designed to provide a desired output voltage or termination voltage for various applications by converting voltage supplies ranging from 1.6V to 6.0V. The desired output voltage could be programmable by two external voltage divider resistors. The AP1127 is capable of sourcing or sinking up to 3A of current while regulating an output VOUT voltage to within 2% (DDR-I), 3%(DDR-II) or less. The AP1127 provides low profile 5-lead TO-252 package to save system space.
