    LMZ10503TZX-ADJ/NOPB

    The LMZ10503 power module is a complete, easy-touse DC-DC solution capable of driving up to a 3-A
    load with exceptional power conversion efficiency,
    output voltage accuracy, line and load regulation. The
    LMZ10503 is available in an innovative package that
    enhances thermal performance and allows for hand
    or machine soldering.
    The LMZ10503 can accept an input voltage rail
    between 2.95 V and 5.5 V and can deliver an
    adjustable and highly accurate output voltage as low
    as 0.8 V. One megahertz fixed-frequency PWM
    switching provides a predictable EMI characteristic.
    Two external compensation components can be
    adjusted to set the fastest response time, while
    allowing the option to use ceramic and/or electrolytic
    output capacitors. Externally programmable soft-start
    capacitor facilitates controlled startup. The LMZ10503
    is a reliable and robust solution with the following
    features: lossless cycle-by-cycle peak current limit to
    protect for over current or short-circuit fault, thermal
    shutdown, input undervoltage lockout, and prebiased
    start-up.
