    MP20051 0.8-5V, 1A Linear Regulator SOIC8E

    The MPS MP20051 is a Linear Regulator. It operates from a 0.8 V to 5 V input and is rated for 1 A. It is supplied in a SOIC8E package.

    The MP20051 is a low-dropout linear regulator that supplies up to 1A current with a 140mV dropout voltage.

    Design Notes

    • Dissipation is (VIN − VOUT) × IOUT. Check it against the package thermal resistance at the real ambient temperature before committing to the full rated current.
    • Some low-noise LDOs require a minimum output capacitor ESR for loop stability — read the stability section before substituting a ceramic part.
    • Add a bypass capacitor on the reference pin where provided; it sets the output noise floor.
    • PSRR falls as the input-to-output differential shrinks, so headroom matters at low VIN.
