Description

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. Typical ground pin current (quiescent current) is 65µA with no load, and less than 1µA in shutdown mode.
