    LMZ14203TZX-ADJ/NOPB

    The LMZ14203 SIMPLE SWITCHER power module
    is an easy-to-use step-down DC-DC solution that can
    drive up to 3-A load with exceptional power
    conversion efficiency, line and load regulation, and
    output accuracy. The LMZ14203 is available in an
    innovative package that enhances thermal
    performance and allows for hand or machine
    soldering.
    The LMZ14203 can accept an input voltage rail
    between 6 V and 42 V and deliver an adjustable and
    highly accurate output voltage as low as 0.8 V. The
    LMZ14203 only requires three external resistors and
    four external capacitors to complete the power
    solution. The LMZ14203 is a reliable and robust
    design with the following protection features: thermal
    shutdown, input UVLO, output overvoltage protection,
    short-circuit protection, output current limit, and
    allows start-up into a prebiased output. A single
    resistor adjusts the switching frequency up to 1 MHz.
