LTC1517-3.3

Micropower, Regulated

3.3V Charge Pump in a

5-Pin SOT-23 Package

FEATURES

DESCRIPTION

The LTC^®1517-3.3 is a micropower charge pump DC/DC

converter that produces a regulated 3.3V output. 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

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 0.045in².

Available in 5-Pin SOT-23

The part operates as a Burst Mode^TMswitched-capacitor

voltage doubler to produce a regulated output. The part has

thermal shutdown capability and can survive a continuous

short circuit from V_OUTto GND. The device is available in a

5-pin SOT-23 package.
