  • The ST715 is a high voltage, ultra low quiescent current and low drop linear regulator capable of providing an output current in excess of 85 mA.

    The device operates over an input voltage range from 2.5 V to 24 V, and it is stable with output ceramic capacitors. Fault condition protection includes short-circuit current limitation. The ultra low quiescent current of 3.8 μA at full load makes it highly suitable for low power applications and battery-powered systems. The wide input voltage range makes the ST715 an ideal solution for low power industrial applications. The ST715 is available in SOT23-5, SOT323-5L or DFN8 (3x3 mm) 8 leads.

    Key Features

    • 2.5 V to 24 V input voltage
    • Low-dropout voltage (500 mV typ. at 85 mA)
    • Very low quiescent current (3.8 μA typ. at full load)
    • 85 mA guaranteed output current
    • Output voltages available on request: from 1.2 V to 5.0 V with 100 mV step and adjustable
    • Compatible with ceramic output capacitors from 0.47 μF to 10 μF
    • Internal current limit
    • Packages: SOT23-5L, SOT323-5L and DFN8 (3x3 mm)
    • Temperature range: from -40 °C to 125 °C
