  • The LD39050 provides 500 mA maximum current with an input voltage range from 1.5 V to 5.5 V and a typical dropout voltage of 200 mV. Stability is given by ceramic capacitors. The ultra low drop voltage, low quiescent current and low noise features make it suitable for low power batterypowered applications. Power supply rejection is 65 dB at low frequencies and starts to roll off at 10 kHz. The enable logic control function puts the LD39050 in shutdown mode allowing a total current consumption lower than 1 μA. The device also includes short-circuit constant current limiting and thermal protection. Typical applications are mobile phones, hard disks and battery-powered systems.

    Key Features

    • Input voltage from 1.5 to 5.5 V
    • Ultra low-dropout voltage (200 mV typ. at 500 mA load)
    • Very low quiescent current (20 μA typ. at no load, 100 μA typ. at 500 mA load, 1 μA max. in OFF mode)
    • Very low noise without bypass capacitor
    • Output voltage tolerance: ± 2.0% @ 25 °C
    • 500 mA guaranteed output current
    • Wide range of output voltages available on request: 0.8 V to 4.5 V with 100 mV step and adjustable from 0.8 V
    • Logic-controlled electronic shutdown
    • Compatible with ceramic capacitor COUT = 1 μF
    • Internal current and thermal limit
    • Package DFN6 (3x3 mm) and DFN6 (2x2 mm)
    • Temperature range: from -40 °C to 125 °C
