DESCRIPTIONThe REG711 is a switched capacitor voltage con-
verter, which 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
REG711 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 regula-
tion. It works equally well for step up or down 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 REG711 is thermally
protected and current limited, protecting the load and
the regulator during fault conditions. Typical ground
pin current (quiescent current) is 1mA at full load,
60μA with no load, and less than 1μA in shutdown
mode. This regulator comes in a thin MSOP-8 pack-
age with a component height of less than 1.1mm.
