3 Description

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.
