∗) Tab and tab suspension leads in the parts are GND level.
(They are connected to the reverse side of the IC.)
The tab is better to be connected to the GND, but leaving it open is also acceptable.
The tab suspension leads should be open and do not connect to other wires or land patterns.
∗1) The VOUT pin and VDD pin must be wired each other when it is mounted on board.
