  • The LD56050 is a high accuracy voltage regulator, which provides 0.5 A of current. It is equipped with an NMOS pass transistor, whose gate is biased by a dedicated pin, thus allowing an ultra low-drop performance even at very low input voltages.

    It is available in DFN4 1.2 x 1.2 package, allowing the maximum space saving.
    The device is stabilized with a small ceramic capacitor on the output. The ultra low-drop, low quiescent current and short circuit current foldback make the LD56050 suitable for low power battery-operated applications.
    An enable logic control function puts the LD56050 in shutdown mode allowing a total current consumption lower than 0.1 µA. Thermal protection is also included.

    主要特性

    • Input voltage from 0.8 to 5.5 V
    • Bias supply pin
    • Ultra low-dropout voltage (120 mV max. at 500 mA load)
    • Low ground current (27 μA typ. at no-load)
    • Output voltage tolerance: ± 1.5% overtemperature, 0.5% at 25 °C
    • 500 mA guaranteed output current
    • 50 mV output voltage step available from 0.8 V to 3.6 V
    • Logic-controlled electronic shutdown
    • Internal current limit with foldback
    • Thermal shutdown
    • Output active discharge function
    • Available in DFN4 1.2 x 1.2 mm package
    • Temperature range: -40 °C to 85 °C
