ST732 Datasheet | STMicroelectronics

Features - Wide input voltage range : 2.5 V to 28 V - Ultra-low quiescent current: typ. 5 µA at no-load, 10 µA max. across full temperature range - Output voltage accuracy: ± 2% - Output current up to 300 m A - Fixed output voltage versions, starting from 1.2 V with 100 m V step - Stable with low ESR capacitors (0.47 µF min.) - Thermal shutdown protection - Current limit protection - -40 °C to +125 °C operating temperature range Applications - Post regulation - Electronic meters - Smoke detectors / alarms - Portable equipment - Industrial applications Description The ST732 is 300 m A 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 ST732 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.
