General Description

        ET5H4XX series are the high input very low IQ 300mA LDO with enable function that operates from 1.8V~5V, is designed specifically for portable battery-powered applications which require ultra-low quiescent current. The very-low consumption of type 2uA ensures long battery life and dynamic transient boost feature improves device transient response for wireless communication applications.

        ET5H4XX series are offered SOT89-3, SOT89-5,SOT23-5, SOT23-3, DNF4(1x1) packages
