  • The ST1L08 provides 0.8 A of maximum current from an input voltage in the range from 1 V to 5.5 V, with a typical dropout voltage as low as 70 mV.

    It is stabilized with a ceramic capacitor on the output.
    The very low drop voltage, low quiescent current and high PSRR features make it suitable for low power battery-powered applications.
    Enable logic control function puts the ST1L08 in shutdown mode, reducing the total current consumption.
    Power Good function and input voltage control feature the ST1L08Sxx version.
    The device is equipped with current limit and thermal protection.

    Key Features

    • Input voltage from 1 to 5.5 V
    • Ultra low-dropout voltage (90 mV max. @ 800 mA load)
    • Low ground current (35 μA typ. @ no load)
    • Output voltage tolerance: ± 2.0% @ 25 °C
    • High PSRR: 80 dB @ 100 Hz, 50 dB @1 MHz
    • 800 mA guaranteed output current
    • Wide range of output voltages available on request: from 0.5 V to 4 V and adjustable
    • Logic-controlled electronic shutdown
    • Internal current and thermal limit
    • Power Good function
    • Available in DFN8 2x3 mm package
    • Temperature range: -40 °C to 125 °C
    • Input voltage control for the ST1L08Sxx
