The AP7344 supports input voltages from 1.7V to 5.25V enabling it to cover the full range of Li+ batteries typically found in portable electronics systems. It provides a regulated output voltage, VOUT, that can be fixed between 1.2V and 3.6V, with an accuracy of 1% at +25 degrees C, and is capable of driving 300mA loads. Other key performance features of this regulator include: low RDSON, a high PSRR of 75dB at 1kHz, low output noise of 60μVrms, and a low 50μA quiescent current that contributes to power savings, which lengthens battery life.
