Texas Instruments REG71055

the reg710 is a switched capacitor voltage converterthat produces a regulated low-ripple output voltage from an unregulated input voltage. a wide input supply voltage of 1.8v to 5.5v makes the reg710 ideal for a variety of battery sources such as single-cell li-ion or two- and three-cell nickel- or alkaline-based chemistries. the input voltage may vary above and below the output voltage and the output remains in regulation. it works equally well for step-up or step-down applications without the need for an inductor providing low emi dc/dc conversion. the high switching frequency allows the use of small surface-mount capacitors saving board space and reducing cost. the reg710 is thermally protected and current limited protecting the load and the regulator during fault conditions. view all in datasheet
