3.0
The descriptions of the pins are listed in Table 3-1.
TABLE 3-1:
3.1
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,
output voltage falls to zero, and supply current is
reduced to 0.05 µA (typ.)
3.2
For best performance, it is recommended that the
ground pin be tied to a ground plane.

Bypass the regulated voltage output to GND with a
minimum capacitance of 1 µF. A ceramic bypass
capacitor is recommended for best performance.
