Part Number : MAX682
Function : 3.3V-Input to Regulated 5V-Output Charge Pumps / 2.7V to 5.5V Input Voltage
Package : SO 8 Pin Type
Maker : Maxim Integrated
Pinouts : 
Description :
The MAX682 / MAX683 / MAX684 charge-pump regulators generate 5V from a 2.7V to 5.5V input. They are specifically designed to serve as high-efficiency auxiliary supplies in applications that demand a compact design. The MAX682, MAX683, and MAX684 deliver
250mA, 100mA, and 50mA output current, respectively.
These complete 5V regulators require only one resistor and three external capacitors—no inductors are need ed. High switching frequencies (externally adjustable up to 2MHz) and a unique regulation scheme allow the use of capacitors as small as 1µF per 100mA of output
current.
Features
* 1.1mm Height in µMAX Package (MAX683/MAX684)
* Up to 250mA Output Current (MAX682)
* Regulated ±4% Output Voltage
