The REG711 is a switched capacitor voltage converter which generates a regulated output voltage that ripples from an unregulated low input voltage. The wide input supply voltage is 1.8V to 5.5V, making battery sources such as single-cell lithium-ion or two or three cell nickel or alkaline chemicals ideal for a variety of REG711.

Input voltages may vary above and below the output voltage and output will remain in regulation. It also applies without requiring an inductor to rise or fall, providing low EMI DC/DC conversion. The high switching frequency allows the use of small surface mount capacitors, saving board space and reducing cost of ownership. The REG711 is thermally protected and current limiter, protecting loads and regulators under fault conditions.
