DESCRIPTION
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.
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 65
μ
A with no load, and less than 1
μ
A 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.
