Note 1: Operating Characteristics are over Standard Operating Conditions unless otherwise specified.

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.
