The MAX5008 charge-pump regulator generates a regulated5V output up to 125mA with a 2.95V to 5.5V inputvoltage range. The device includes resistor-programmableovercurrent limit. The MAX5008 requires a minimumnumber of external components for normaloperation. The high 1MHz switching frequency allowsthe use of small surface-mount ceramic capacitors.The fault-protection circuitry limits the output currentwhen it exceeds the limit set by an external resistor.The output current can range from 1mA to 150mA toaccommodate circuit requirements. A FAULT outputindicates when the device is in current limit or the outputis out of regulation.A low-power shutdown mode reduces supply current toless than 1μA and places the output in a high-impedancestate. The MAX5008 is offered in a space-saving10-pin μMAX® package that is only 1.1mm high.ApplicationsFlash Memory SuppliesUSB Host DevicesBattery-Powered Systems3.3V to 5V Local Conversion
