LM3686 Datasheet (Texas Instruments) - Step-Down DC-DC Converter

LM3686, Step-Down DC-DC Converter

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 combined load current up to 900 mA over an input voltage range from 2.7 V to 5.5 V.
