Note 1: The power rating is based on a printed circuit board heat spreading capability equivalent to 2 square inches of copper connected to

the GND pins. Typical multilayer boards using power plane construction will provide this heat spreading ability without the need for

additional dedicated copper area. (Please consult with factory for thermal evaluation assistance.)

Note 2: The hysteresis defines the maximum level of acceptable disturbance on V

CC during switching. It is recommended that the VCC

source impedance be kept below 0.25

Ω to ensure the switching disturbance remains below the hysteresis during select/deselect

transitions. An input capacitor may be required to help minimize the switching transient.

Note 3: Ground pin current consists of controller current (0.15mA) and regulator current if enabled. The controller always draws 0.15mA

from either V

CC or VOUT, whichever is greater. All regulator current is supplied exclusively from VCC. At high load currents a small

increase occurs due to current limit protection circuitry.
