3.2
Connect the unregulated input supply ground return to
GND. Also connect one side of the 1 µF typical input
decoupling capacitor close to this pin and one side of
the output capacitor C
3.3
The regulator is fully enabled when a logic-high is
applied to SHDN. The regulator enters shutdown when
a logic-low is applied to this input. During shutdown, the
output voltage falls to zero and the supply current is
reduced to 0.5 µA (maximum).
