The MAX5008 charge-pump regulator generates a regulated 5V output up to 125mA with a 2.95V to 5.5V input voltage range. The device includes resistor-programmable overcurrent limit. The MAX5008 requires a minimum number of external components for normal operation. The high 1MHz switching frequency allows the use of small surface-mount ceramic capacitors. The fault-protection circuitry limits the output current when it exceeds the limit set by an external resistor. The output current can range from 1mA to 150mA to accommodate circuit requirements. A FAULT output indicates when the device is in current limit or the output is out of regulation. A low-power shutdown mode reduces supply current to less than 1μA and places the output in a high-impedance state. The MAX5008 is offered in a space-saving 10-pin μMAX® package that is only 1.1mm high. Applications Flash Memory Supplies USB Host Devices Battery-Powered Systems 3.3V to 5V Local Conversion
