Description

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. The ST730 embeds protection functions, such as: current limit, short-circuit and thermal shutdown. The extended input voltage range, very low drop voltage and low quiescent current features make it suitable also for low power after-market automotive and consumer applications.
