Note 1: At rated load, the power dissipation will be 0.68Watt (1.7V x 0.4A). Under these conditions, (in a 70°C ambient), the thermal

resistance from junction to ambient (θJA) must not exceed 80°C/W. This is typically achieved with 2 square inches of copper

printed circuit board area connected to the GND pins for heat spreading, or equivalent.
