Sales Briefcase

  • The LD39030SJ is a low noise voltage regulator that provides 300 mA maximum current from an input voltage in the 1.5 V to 5.5 V range, with a typical dropout voltage of 200 mV. It is stabilized with a ceramic capacitor on the output. The ultra low drop voltage, low quiescent current, and low noise features make it suitable for low power battery-powered applications. Power supply rejection is typically 62 dB at low frequencies and starts to roll off at 10 kHz. An enable logic control function puts the LD39030SJ in shutdown mode allowing a total current consumption lower than 1 μA. The device also includes a short-circuit constant current limiting and thermal protection.

    Key Features

    • Input voltage from 1.5 to 5.5 V
    • Ultra low dropout voltage (200 mV typ. at 300 mA load)
    • Very low quiescent current (20 μA typ. at no load, 40 μA typ. at 300 mA load, 1 μA max. in off mode)
    • Very low noise (30 μVRMSfrom 1 kHz to 100 kHz at VOUT= 1.8 V)
    • Output voltage tolerance: ± 2.0 % @ 25 °C
    • 300 mA guaranteed output current
    • Wide range of output voltages available on request: 0.8 V to 4.5 V with 100 mV step
    • Logic-controlled electronic shutdown
    • Compatible with ceramic capacitor COUT = 1 μF
    • Internal current and thermal limit
    • Flip-chip 4 bumps 0.8 x 0.8 mm pitch 0.4 mm
    • Internal soft-start (typ. 100 μs)
    • Temperature range: - 40 °C to 125 °C
