  • The LD39150 is a fast ultra low drop linear regulator which operates from 2.5 V to 6 V input supply.

    A wide range of output options are available. The low drop voltage, low noise, and ultra low quiescent current make it suitable for low voltage microprocessor and memory applications. The device is developed on a BiCMOS process which allows low quiescent current operation independently of output load current.

    主要特性

    • 1.5 A guaranteed output current
    • Ultra low dropout voltage (200 mV typ. @ 1.5 A load, 40 mV typ. @ 300 mA load)
    • Very low quiescent current (1 mA typ. @ 1.5 A load, 1 μA max @ 25 °C in off mode)
    • Logic-controlled electronic shutdown
    • Current and thermal internal limit
    • ± 1.5% output voltage tolerance @ 25 °C
    • Fixed and ADJ output voltages: 1.8 V, 2.5 V, 3.3 V, ADJ
    • Temperature range: -40 to 125 °C
    • Fast dynamic response to line and load changes
    • Stable with ceramic capacitor
    • Available in PPAK, DPAK and DFN6 (3x3 mm)
