The CE021is a low noise, constant frequency (1.2MHz) switched capacitor voltagedoubler.
It produce a regulated output voltagefrom a 1.8V to 5V input with up to 100mA of output current.Low external parts count (one flying capacitor and two small bypasscapacitors at VIN and VOUT) make theCE021 ideally suited for small,battery-powered applications.
   
The CE021 have thermal shutdown capability and can survive a continuous short circuit from VOUT to GND. Built-in soft-start circuitry prevents excessive inrush current during start-up.
  
High switching frequency enables the use of small ceramic capacitors. A low current shutdown feature disconnects the load from VIN and reduces quiescent current to <1uA.

Attention :
 
This is a DC-DC voltage converter module,Must be noted when using:
1 Input voltage can not be greater than the maximum input range
2 Output power can not be greater than the maximum load for a long time
3 Input power must be greater than the output power, because the power consumption of the module itself
