Product overview

Description

The LDL112 is a low-dropout linear regulator, which can provide a maximum current of 1.2 A, with a typical dropout voltage of 300 mV. It is stabilized with a ceramic capacitor on the output. The very low drop voltage, low quiescent current and reverse current protection features make it suitable for low power battery-powered applications. The enable logic control function puts the LDL112 in shutdown mode allowing a total current consumption lower than 1 μA. The device is equipped with current limit and thermal protection.

  • All features

    • Input voltage from 1.6 to 5.5 V
    • Very low-dropout voltage (300 mV typ. at 1 A load)
    • Low quiescent current (35 μA typ. at no-load, 1 μA max. in off mode)
    • Output voltage tolerance: ± 2.0% at 25 °C
    • 1.2 A guaranteed output current
    • Wide range of output voltages available on request: 0.8 V to 5 V with 50 mV step and adjustable
    • Logic-controlled electronic shutdown
    • Compatible with ceramic capacitor COUT = 1 μF
    • Internal current and thermal limit
    • Available in DFN6 (2x2), DFN6 (3x3) mm, SO8-batwing and PPAK packages
    • Temperature range: -40 °C to 125 °C
    • Reverse current protection
    • Output discharge function (optional)
