    LTC3035
    300mA VLDO Linear
    Regulator with Charge Pump
    Bias Generator U FEATURES DESCRIPTIO ■ The LTC®3035 is a micropower, VLDO™ (very low dropout) linear regulator which operates from input voltages as
    low as 1.7V. The device is capable of supplying 300mA of
    output current with a typical dropout voltage of only
    45mV. To allow operation at low input voltages the LTC3035
    includes a charge pump generator that provides the necessary bias voltage for the internal LDO circuitry. Output
    current comes directly from the input supply for high
    efficiency regulation. The charge pump bias generator
    requires only a 0.1µF flying capacitor and a 1µF bypass
    capacitor for operation. The low 0.4V internal reference
    voltage allows the LTC3035 to be programmed to much
    lower output voltages than commonly available in LDOs.
    The output voltage is programmed via two tiny SMD
    resistors. The LTC3035’s low quiescent current makes it
    an ideal choice for use in battery-powered systems. ■
