  • The STEVAL-ISB037V1 board features the LD39020 high performance linear voltage regulator, configured to convert a DC input voltage from 2.4 V to 5.5 V into a precise and stable 1.8 V output voltage.

    Only two small ceramic capacitors are needed to implement the linear regulator solution.
    The very low dropout LD39020 voltage regulator features high PSRR and low quiescent current in a tiny DFN4 package with a footprint of only (1 x 1) mm².
    It is designed for low-power battery operated equipment such as smartphones, tablets and wearable devices.

    Key Features

    • Output current: 200 mA
    • Logic controlled electronic shutdown
    • High PSRR
      • 80 dB @ 1 kHz
      • 50 db @ 100 kHz
    • Quiescent current:
      • 20 μA typ at no load
      • 0.03 μA typ in off mode
    • 1.8 V ± 0.5% output voltage
    • Other voltage options available on request
    • DFN4-1 x 1 package (0.8 x 0.8 available on request)
    • RoHS compliant
