For the DFN package, the center exposed pad is a thermal
Pad
path to remove heat from the device. Electrically this pad is at
ground potential and should be connected to GND
3.1
Power Supply Input Voltage Pin
3.4
Feedback / Output Voltage Pin
(V IN )
Connect the input voltage source to V IN . The input
source must be decoupled to GND with a 4.7 μF
capacitor.
(V FB /V OUT )
For adjustable output options, connect the center of the
output voltage divider to the V FB /V OUT pin. For fixed-
output voltage options, connect the output directly to
3.2
Ground Pin (GND)
the V FB /V OUT pin.
Ground pin for the device. The loop area of the ground
traces should be kept as minimal as possible.
3.5
Switch Node, Buck Inductor
Connection Pin (L X )
3.3
Shutdown Control Input Pin
(SHDN)
Connect the L X pin directly to the buck inductor. This
pin carries large signal-level current; all connections
should be made as short as possible.
The SHDN pin is a logic-level input used to enable or
disable the device. A logic high (> 45% of V IN ) will
enable the regulator output. A logic-low (< 15% of V IN )
will ensure that the regulator is disabled.

3.6 Exposed Metal Pad (EP)
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.
