The REG710 family of devices are switched capacitor voltage converters that generate regulated, low-ripple output voltage from an unregulated input voltage. A wide input supply voltage from 1.8 V to 5.5 V makes the REG710 family of devices ideal for a variety of battery sources, such as single-cell Li-Ion, or 2-cell and 3-cell nickel-based or alkaline-based chemistries.

The input voltage may vary above and below the output voltage and the output remains in regulation. The device works as step-up or step-down converters without the need of 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 device is thermally protected and current limited, protecting the load and the regulator during fault conditions. Typical ground pin current (quiescent current) is 65 μA with no load, and less than 1 μA in shutdown mode.
