ST730 Low-Dropout (LDO) Voltage Regulator

STMicroelectronics ST730 Low-Dropout (LDO) Voltage Regulator is a 300mA regulator designed for several medium voltage applications. Ultra-low quiescent current of 5μA makes it suitable for applications permanently connected to a 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, low drop voltage, and low quiescent current features make it suitable for low-power after-market automotive and consumer applications.
