  • The LD39200 provides 2 A of maximum current with an input voltage range from 1.25 V to 6.0 V, and a typical dropout voltage of 130 mV.

    It is stable with ceramic capacitors on the output (10 µF).
    Typical power supply rejection ratio is 70 dB at 1 kHz and starts to roll off at 20 kHz.
    The enable logic control function puts the LD39200 in shutdown mode, reducing the total current consumption to 10 nA (typ.).
    Power Good flag is available on a dedicated pin.
    The device also includes reverse current protection, short-circuit constant current limit and thermal protection.
    Typical applications are for Telecom infrastructure and consumer.

    Key Features

    • Input voltage from 1.25 V to 6.0 V
