The descriptions of the pins are listed in
TABLE 3-1:
3.1
Connect unregulated input supply to the V
there is a large distance between the input supply and
the LDO regulator, some input capacitance is
necessary for proper operation. A 1 µF capacitor
connected from V
most applications.
3.2
Connect the unregulated input supply ground return to
GND. Also connect the negative side of the 1 µF typical
input decoupling capacitor close to GND and the
negative side of the output capacitor C

The regulator is fully enabled when a logic-high is
applied to SHDN. The regulator enters shutdown when
a logic-low is applied to SHDN. During shutdown,
output voltage falls to zero, ERROR is open-circuited
and supply current is reduced to 0.5 µA (max).
