Sales Briefcase
  • The LDBL20 high accuracy voltage regulator provides 200 mA of maximum current from an input voltage ranging from 1.5 V to 5.5 V, with a typical dropout voltage of 200 mV.

    It is available in the new STSTAMP™ package, allowing the maximum space saving.
    The device is stabilized with a ceramic capacitor on the output. The ultra low drop voltage, low quiescent current and low noise features, together with the internal soft-start circuit, make the LDBL20 suitable for low power battery-operated applications.
    An enable logic control function puts the LDBL20 in shutdown mode with a total current consumption lower than 0.2 µA. Constant current and thermal protection are provided.

    Key Features

    • Input voltage from 1.5 to 5.5 V
    • Ultra low-dropout voltage (200 mV typ. at 200 mA load)
    • Very low quiescent current (20 µA typ. at no-load, 0.03 µA typ. in off mode)
    • Output voltage tolerance: ± 1.5% @ 25 °C
    • 200 mA guaranteed output current
    • High PSRR (80 dB@1 kHz, 50 db@100 kHz)
    • Wide range of output voltages available on request: from 0.8 V up to 5.0 V in 50 mV step
    • Logic-controlled electronic shutdown
    • Internal soft-start
    • Optional output voltage discharge feature
    • Compatible with ceramic capacitor COUT = 0.47 µF
    • Internal constant current and thermal protections
    • Available in STSTAMP™ (0.47x0.47) mm² package
    • Operating temperature range: -40 °C to 125 °C
