■ 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
