General part information

The ST730 is 300 mA LDO regulator, designed to be used in several medium voltage applications.

Ultra-low quiescent current of 5 μA makes it suitable for applications permanently connected to power supply/battery.

This feature is also useful when electronic modules remain permanently turned on.
