SO-8EP
GND 2 1 Ground.
IN 1 2, 3, 4 Voltage input pin.
OUT 3 5, 6, 7 Voltage output pin.
ADJ NA 8
Output feedback pin for adjustable version only – a resistor divider from this pin to the OUT
pin and ground sets the output voltage.
NC NA 8 No connection for fixed output version.
EP/TAB — —
The exposed pad (EP) is used to remove heat from the package and it is recommended that
it is connected to a copper area. The die is electrically connected to the exposed pad. It is
recommended to connect it externally to GND, but should not be the only ground connection.
