3.0
The descriptions of the pins are listed in
TABLE 3-1:
3.1
Connect the input voltage source to V
source must be decoupled to GND with a 4.7 µF
capacitor.
3.2
Ground pin for the device. The loop area of the ground
traces should be kept as minimal as possible.
3.3
The SHDN pin is a logic-level input used to enable or
disable the device. A logic high (> 45% of V
enable the regulator output. A logic-low (< 15% of V
will ensure that the regulator is disabled.

For the DFN package, the center exposed pad is a thermal
path to remove heat from the device. Electrically this pad is at
ground potential and should be connected to GND
3.4
For adjustable output options, connect the center of the
output voltage divider to the V
output voltage options, connect the output directly to
the V
3.5
Connect the L
pin carries large signal-level current; all connections
should be made as short as possible.
3.6
For the DFN package, connect the Exposed Pad to
GND, with vias into the GND plane. This connection to
the GND plane will aid in heat removal from the
package.
