  • 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
    • Ultra low drop: 130 mV (typ.) at 2 A load
    • 1 % output accuracy at 25 °C, 2 % in full temperature range
    • High PSRR: 70 dB at 1 kHz
    • Reverse current protection
    • 2 A guaranteed output current
    • Available in fixed and adjustable output voltage version from 0.5 V with 100 mV step
    • Power Good
    • Internal current and thermal limit
    • Operating junction temperature range: -40 °C to 125 °C
    • DFN6 (3 x 3 mm) and DFN8 (4 x 4 mm) packages
