Note 1: The maximum power dissipation of this device is internally limited by thermal shutdown circuitry. To achieve a power dissipation of 3.0
watts, a case-to-ambient thermal resistance of 25°C/W must be provided. This will typically require dedicated heatsinking ability of the
printed circuit board. For more details, please see the Typical Thermal Characteristics section.
Note 2: The hysteresis defines the maximum level of acceptable disturbance on VCC during switching. It is recommended that the VCC source
impedance be kept below 0.15Ω to ensure the switching disturbance remains below the hysteresis during select/deselect transitions.
Note 3: Ground pin current consists of controller current (0.2mA) and regulator current when selected
