Absolute Maximum Ratings
All voltages referenced to GND pin.
**The power dissipation is given for the standard minimum pad without a heat
slug, and based on R
and case-to-ambient thermal resistance, where the latter is determined by
the user’s board design. The junction-to-ambient thermal resistance is R
105°C/W when the part is mounted on a 0.04 in
