Note 1:

Note 3:
The thermal resistance from junction to ambient (θJA) must be less than 55° 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.
The hysteresis defines the maximum level of acceptable disturbance on VCC during switching.
Ground current consists of controller current and regulator current if enabled.
