Connect a 1µF ceramic input capacitor as close to the
device as possible. Provide a large copper GND plane
to allow the exposed paddle to sink heat away from the
device. Connect the battery to BATT as close to the
device as possible to provide accurate battery voltage
sensing. Make all high-current traces short and wide to
minimize voltage drops. For an example layout, refer to
the MAX1507/MAX1508 evaluation kit layout.
