Note 1: At rated load, the power dissipation will be 0.68W (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.
Note 2: The disturbance on VCC during supply changeover should be kept below the hysteresis voltage to prevent any chatter. The source
resistance on the VCC supply should be kept to less than 0.3Ω to ensure precise switching.
