... Regulated 5V-Output Charge Pumps Detailed Description The MAX682/MAX683/MAX684 charge pumps provide a regulated 5V output from a 2.7V to 5.5V input. They deliver a maximum of 250mA, 100mA, or 50mA load current, respectively. Designed specifically for com- pact applications, a complete regulator circuit requires only three small external capacitors and one resistor. ...

... In continuous switching mode, smaller output rip- ple allows smaller C required to maintain low output ripple. Tables 2 and 3 show capacitor values recommended for lowest sup- ply-current operation (skip mode) and smallest size oper- ation (constant-frequency mode), respectively.
