  • The LD57100 is a high accuracy voltage regulator, which provides 1 A of current. It is equipped with an NMOS pass transistor, whose gate is biased by a dedicated pin, thus allowing the ultra-low drop performance even at very low input voltages.

    It is available in Flip Chip6 (0.8x1.2 mm), maximizing the space saving. This device is stabilized with a small ceramic capacitor on the output. The ultra low drop, low quiescent current and short-circuit protection make the LD57100 suitable for low power battery-operated applications.
    An enable logic control function puts the LD57100 in shutdown mode allowing a total current consumption lower than 0.1 µA. Thermal protection is also included.

    Key Features

    • Input voltage from VOUT to 5.5 V
    • Input bias supply pin from 3.0 V to 5.5 V
    • Ultra low-dropout voltage (40 mV typ. at 1 A load)
    • Low ground current (35 μA typ. at no load)
    • Output voltage tolerance: ±1% all over temperature range, ±0.5% at 25 °C
    • 1 A guaranteed output current
    • 50 mV output voltage step available from 0.4 V to 1.8 V
    • 100 mV output voltage step available from 1.9 V to 3.6 V
    • Adjustable version from 0.5 V to 3.0 V
    • Logic-controlled electronic shutdown
    • Internal current limit
    • Thermal shutdown
    • Output active discharge function
    • Available in Flip Chip6 (0.8x1.2 mm) package
    • Temperature range: -40 °C to 85 °C
