    LT1965EMS8E#PBF

    The LT®1965 series are lownoise, lowdropout linearregulators. The devices supply 1.1A of output current with a
    310mVtypicaldropoutvoltage. Operatingquiescentcurrent
    is 500µA for the adjustable version, reducing to <1µA in
    shutdown. Quiescent current iswell controlled; it does not
    rise in dropout aswithmany otherregulators. The LT1965
    regulators have very low output noise which makes them
    ideal for sensitive RF and DSP supply applications.
    Output voltage ranges from 1.20V to 19.5V. The LT1965
    regulators are stable with output capacitors as low as
    10µF. Internalprotectioncircuitry includes reverse-battery
    protection, current limiting with foldback, thermal limiting and reverse-current protection. The LT1965 series
    are available in fixed output voltages of 1.5V, 1.8V, 2.5V,
    3.3V, and as an adjustable device with a 1.20V reference
    voltage. The package offerings include the 5-lead TO-220,
    5-lead DD-Pak as well as the thermally enhanced 8-lead
    MSOP and lowprofile (0.75mm) 8-lead 3mm× 3mmDFN.
