    300mA Micropower
    VLDO Linear Regulator
    FEATURES DESCRIPTION n The LTC®3025 is a micropower, VLDOTM (very low dropout) linear regulator which operates from input voltages as
    low as 0.9V. The device is capable of supplying 300mA of
    output current with a typical dropout voltage of only 45mV.
    A BIAS supply is required to run the internal reference and
    LDO circuitry while output current comes directly from
    the IN supply for high efficiency regulation. The low 0.4V
    internal reference voltage allows the LTC3025 output to
    be programmed to much lower voltages than available in
    common LDOs (range of 0.4V to 3.6V). The output voltage
    is programmed via two ultrasmall SMD resistors. n Wide Input Voltage Range: 0.9V to 5.5V
    Stable with Ceramic Capacitors
    Very Low Dropout: 45mV at 300mA
    Adjustable Output Range: 0.4V to 3.6V
    ±2% Voltage Accuracy over Temperature
    Supply Load
    Low Noise: 80μVRMS (10Hz to 100kHz)
    BIAS Voltage Range: 2.5V to 5.5V
    Fast Transient Recovery
    Shutdown Disconnects Load from VIN and VBIAS
    Low Operating Current: IIN = 4μA, IBIAS = 50μA Typ ...
