FEATURES

DESCRIPTION

Wide Input Range: 1.8V to 5.5V

The REG710 is a switched capacitor voltage converter,

that 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.

Automatic Step-Up/Step-Down Operation

Low Input Current Ripple

Low Output Voltage Ripple

Minimum Number of External

ComponentsNo Inductors

1MHz Internal Oscillator Allows Small

Capacitors

The input voltage may vary above and below the output

voltage and the output will remain 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. The 5.5V version of the REG710 is

available in a thin TSOT23-6 package. All other versions

are available in a small SOT23-6 package.
