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.

Thermal shutdown protection and current limit and SOA protection

Stable with low ESR capacitors (0.47 μF min.)

-40 °C to +125 °C operating temperature range
