Product overview

Description

The ST732 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 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.
  • All 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 mA
    • Fixed output voltage versions, starting from 1.2 V with 100 mV step
    • Stable with low ESR capacitors (0.47 µF min.)
    • Thermal shutdown protection
    • Current limit protection
    • -40 °C to +125 °C operating temperature range
