The input voltage range is 2V to 4.4V, allowing a single cell lithium battery to produce a regulated 3.3V output over the entire life of the battery. Extremely low operating current (typically 6μA with no load) and low external parts count (one 0.1μF flying capacitor and two small bypass capacitors at V IN and V OUT ) make the part ideally suited for small, light load battery-powered applications. The total printed circuit board area of the application circuit shown below is only 0.045in?.The part operates as a Burst Mode’ switched-capacitor voltage doubler to produce a regulated output. The part has thermal shutdown capability and can survive a continuous short circuit from V OUT to GND. The device is available in a 5-pin SOT-23 package.
