The STMicroelectronics ST730 is 300 mA LDO regulator, designed to be used in several medium voltage applications. It has an ultra-low quiescent current of 5 μA makes it suitable for applications permanently connected to power supply/battery. It is also useful when electronic modules remain permanently turned on. The device embeds protection functions, such as current limit, short-circuit and thermal shutdown. It suitable also for low power after-market automotive and consumer applications, due to extended input voltage range, very low drop voltage and low quiescent current feature.
