■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 and is for reference only.

The mounting condition is please refer to PACKAGING INFORMATION.
