    • Description

    The LP2980-ADJ is a 50 mA adjustable voltage regulator designed to provide ultra low dropout in battery powered applications.

    Using an optimized VIP (vertically Integrated PNP) process, the LP2980-ADJ delivers unequalled performance in all specifications critical to battery-powered designs:

    Adjustable Output: output voltage can be set from 1.23V to 15V.

    Precision Reference: 1.0% tolerance.

    Dropout Voltage: typically 120 mV @ 50 mA load, and 7 mV @ 1 mA load.

    Ground Pin Current: typically 320 µA @ 50 mA load, and 80 µA @ 1 mA load.

    Sleep Mode: less than 1 μA quiescent current when on/off pin is pulled low.

    Smallest Possible Size: SOT-23 package uses minimum board space.

    Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
