SIT14503Q Overview
The SIT14503Q series is a low dropout linear regulator (LDO) with ultra-low quiescent current and a wide input voltage range of 3V to 40V. SIT14503Q provides fixed output of 3.3V and 5V or adjustable outputs from 0.65V to 24V, providing load currents up to 300mA. The quiescent current of the SIT14503Q series is less than 1µA when disabled and less than 6µA at light loads.
