LTC1517ES5-5#TRMPBF

LTC1517-5 is a micropower charge pump DC/DC converter that produces a regulated 5V output. 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 VIN and VOUT) make the part ideally suited for small, light load battery-powered applications. 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 VOUT to GND. It is widely used in application such as cellular telephones, battery-operated equipment, local power supplies, handheld instruments, PCMCIA supplies etc.
