  • The LDK320 is a low drop voltage regulator, which provides a maximum output current of 200 mA from an input voltage in the range of 2.5 V to 18 V, with a typical dropout voltage of 100 mV.

    It is stabilized with a ceramic capacitor on the output.
    The very good dynamic characteristic, combined with low drop voltage and low quiescent current make it suitable for low power battery-powered applications.
    The enable logic control function allows the LDK320 to be in shutdown mode by consuming a total current lower than 1 μA.
    This device also includes a short-circuit current limiting, thermal and SOA protections.

    主要特性

    • Input voltage from 2.5 to 18 V
    • Very low-dropout voltage (100 mV typ. @ 100 mA load)
    • Low quiescent current (typ. 60 μA, 1 μA in off mode)
    • High PSRR: 88 dB@120 Hz
    • Low noise
    • Output voltage tolerance: ± 2.0% @ 25 °C; (±0.5% version available on request)
    • Output current up to 200 mA
    • Wide range of output voltages available on request: fixed from 1.2 V to 12 V with 100 mV step and adjustable
    • Logic-controlled electronic shutdown
    • Compatible with ceramic capacitor COUT = 1 μF
    • Current, SOA and thermal protections
    • Available in SOT23-5L and SOT-89 packages
    • Temperature range: -40 °C to 125 °C
