Part Details:

19-2426; Rev 1; 7/06 Regulated 5V USB Charge Pump with Programmable Current Limit MAX5008 General Description Features The MAX5008 charge-pump regulator generates a reg- Regulated 5V Output Up to 125mA ulated 5V output up to 125mA with a 2.95V to 5.5V inputvoltage range. The device includes resistor-program- Indefinite Short-Circuit Protection mable overcurrent limit. The MAX5008 requires a mini- Adjustable Output Current Limit mum number of external components for normaloperation. The high 1MHz switching frequency allows No Inductors Required the use of small surface-mount ceramic capacitors. 0.1µA Shutdown Current The fault-protection circuitry limits the output current Thermal Shutdown when it exceeds the limit set by an external resistor.The output current can range from 1mA to 150mA to Fault Output Indicates Overcurrent or Output accommodate circuit requirements. A FAULT output Voltage Out of Regulation indicates when the device is in current limit or the out- put is out of regulation. 2.95V to 5.5V Input Voltage Range A low-power shutdown mode reduces supply current to 10-Pin µMAX Package less than 1µA and places the output in a high-imped-ance state. The MAX5008 is offered in a space-saving10-pin µMAX® package that is only 1.1mm high.
