  • The ST730 is 300 mA 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 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.

    Key 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, 1 μA max. in shutdown
    • High output voltage accuracy: ± 0.5% @ 25 °C, ± 2.5% across temperature range
    • Output current up to 300 mA
    • Fixed output voltage versions, starting from 1.2 V to 12 V with 100 mV step
    • Adjustable voltage version, starting from 1.2 V to VIN - VDROP
    • Stable with low ESR capacitors (0.47 µF min.)
    • Thermal shutdown protection
    • Current limit and SOA protection
    • -40 °C to +125 °C operating temperature range
