LM3686 Overview
The LM3686 is a step-down DC-DC converter with a very low-dropout linear regulator and a low-noise linear regulator optimized for powering ultra-low voltage circuits. It provides three outputs with bined load current up to 900 mA over an input voltage range from 2.7 V to 5.5 V. The device offers superior.
