PIN DESCRIPTIONS
The descriptions of the pins are listed in Table 3-1.
TABLE 3-1:
PIN FUNCTION TABLE
3.1
Shutdown Control Input (SHDN)
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 0.05 µA (typ.)
3.2
Ground Terminal
For best performance, it is recommended that the
ground pin be tied to a ground plane.
3.3
Regulated Voltage Output (VOUT)
Bypass the regulated voltage output to GND with a
minimum capacitance of 1 µF. A ceramic bypass
capacitor is recommended for best performance.
3.4
Unregulated Supply Input (VIN)
The minimum VIN has to meet two conditions in order
to ensure that the output maintains regulation:
VIN  2.7V and VIN  [(VR + 2.5%) + VDROPOUT]. The
maximum VIN should be less than or equal to 6V.
Power dissipation may limit VIN to a lower potential in
order to maintain a junction temperature below 125°C.
Refer to Section 5.0 “Thermal Considerations”, for
determining junction temperature.
It is recommended that VIN be bypassed to GND with a
ceramic capacitor.
