Compact dual LDO regulator offers high accuracy

The LDO supports input voltages from 1.7 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, V_OUT, that can be fixed between 1.2 and 3.6V, with an accuracy of 1% at +25°C, and is capable of driving 300mA loads. Other key performance features of this regulator include: low R_DSON, 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.

The AP7344 comes in a small footprint X2-DFN1612-8 package, making it well-suited for the dense PCB layouts typical in portable electronics systems. It offers a competitive alternative to similar industry-standard LDOs with comparable performance but at a lower cost and with the added benefit of higher efficiency under light load operating conditions.
