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.
