LTC3221 Micropower, Regulated 5V or 3.3V Charge Pump in 2 x 2 DFN

The LTC3221 family are micropower charge pump DC/DC converters that produce a regulated output at up to 60mA. The input voltage range is 1.8V to 5.5V. Extremely low operating current (8μA typical at no load) and low external parts count (one flying capacitor and two small bypass capacitors at VIN and VOUT) make them ideally suited for small, battery-powered applications.
