General Description

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.
