Description
The ST732 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. The ST732 embeds protection functions, such as: current limit, short-circuit and
