    Switching Regulator U DESCRIPTIO FEATURES

    ■ The LT ®1614 is a fixed frequency, inverting mode switching reglator that operates from an input voltage as low as
    1V. Utilizing a low noise topology, the LT1614 can generate a negative output down to – 24V from a 1V to 5V input.
    Fixed frequency switching ensures a clean output free
    from low frequency noise. The device contains a lowbattery detector with a 200mV reference and shuts down
    to less than 10µA. No load quiescent current of the LT1614
    is 1mA and the internal NPN power switch handles a
    500mA current with a voltage drop of just 295mV. Better Regulation Than a Charge Pump
    0.1Ω Effective Output Impedance
    – 5V at 200mA from a 5V Input
    600kHz Fixed Frequency Operation
    Operates with VIN as Low as 1V
    1mA Quiescent Current ...
