    LT1611
    Inverting 1.4MHz Switching
    Regulator in SOT-23
    U DESCRIPTIO FEATURES The LT®1611 is the industry’s first inverting 5-lead SOT-23
    current mode DC/DC converter. Intended for use in small,
    low power applications, it operates from an input voltage
    as low as 1.1V and switches at 1.4MHz, allowing the use
    of tiny, low cost capacitors and inductors 2mm or less in
    height. Its small size and high switching frequency enable
    the complete DC/DC converter function to consume less
    than 0.25 square inches of PC board area. Capable of
    generating – 5V at 150mA from a 5V supply or – 5V at
    100mA from a 3V supply, the LT1611 replaces nonregulated
    “charge pump” solutions in many applications. Very Low Noise: 1mVP–P Output Ripple
    – 5V at 150mA from a 5V Input
    Better Regulation Than a Charge Pump
    Effective Output Impedance: 0.14Ω
    Uses Tiny Capacitors and Inductors
    Internally Compensated
    Fixed Frequency 1.4MHz Operation
    Low Shutdown Current: <1µA
    Low VCESAT Switch: 300mV at 300mA
