STMicroelectronics ST730 Low-Dropout (LDO) Voltage Regulator is 300mA regulator, designed to be used in several medium voltage applications. Ultra-low quiescent current of 5μA 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.
Features
Wide input voltage range: 2.5V to 28VUltra-low quiescent current: 5μA (Typ.) at no-load, 10μA (Max.) across the full temperature range, 1μA (Max.) in shutdownHigh output voltage accuracy: ±0.5% @ 25°C, ±1% across temperature rangeOutput current up to 300mA
Applications
Post regulationElectronic metersSmoke detectors / alarms
