Series

* It should be connected the pin No.2 and 5 to the GND pin.

* If the dissipation pad needs to be connected to other pins, it should

be connected to the GND pin.

* Please refer to pattern layout page for the connecting to PCB.

ABSOLUTE MAXIMUM RATINGS

Ta=25℃

All voltages are described based on the GND (AGND and PGND) pin.

(*1) The maximum value should be either VIN+0.3 or +6.2 in the lowest voltage

(*2) The maximum value should be either VIN+0.3 or +4.0 in the lowest voltage

(*3) The power dissipation figure shown is PCB mounted (40mm×40mm, t=1.6mm, Glass Epoxy FR-4).

Please refer to page 11 for details.
