    FEATURES LT3055 Series
    500mA, Linear Regulator
    with Precision Current Limit
    and Diagnostics
    DESCRIPTION n n n n n n The LT®3055 series are micropower, low noise, low dropout
    voltage (LDO) linear regulators. The devices supply 500mA
    of output current with a dropout voltage of 350mV. A 10nF
    bypass capacitor reduces output noise to 25μVRMS in a
    10Hz to 100kHz bandwidth and soft starts the reference.
    The LT3055’s ±45V input voltage rating combined with its
    precision current limit and diagnostic functions make the
    IC an ideal choice for robust, high reliability applications. n n n n n n Output Current: 500mA
    Dropout Voltage: 350mV
    Input Voltage Range: 1.8V to 45V
    Programmable Precision Current Limit: ±10%
    Output Current Monitor: 1/500th of IOUT
    Programmable Minimum IOUT Monitor
    Temperature Monitor: 10mV/°C
    FAULT Indicator: Current Limit, Thermal Limit or
    Minimum IOUT
    Low Noise: 25μVRMS (10Hz to 100kHz)
    Adjustable Output (VREF = VOUT(MIN) = 0.6V)
    Output Tolerance: ±2% Over Load, Line and Temperature ...
