Charge Pump STPUP/STPDN 3V 50mA 8-Pin VSSOP T/R

The REG711 is a switched capacitor voltage converter,which produces a regulated, low ripple outputvoltage from an unregulated input voltage. A wideinput supply voltage of 1.8V to 5.5V makes theREG711 ideal for a variety of battery sources, such assingle cell Li-Ion, or two and three cell Nickel orAlkaline based chemistries.The input voltage may vary above and below theoutput voltage and the output will remain in regulation.It works equally well for step up or down withoutthe need for an inductor, providing low EMI DC/DCconversion. The high switching frequency allows theuse of small surface-mount capacitors, saving boardspace and reducing cost. The REG711 is thermallyprotected and current limited, protecting the load andthe regulator during fault conditions. Typical groundpin current (quiescent current) is 1mA at full load,60µA with no load, and less than 1µA in shutdownmode. This regulator comes in a thin MSOP-8 packagewith a component height of less than 1.1mm.
