CMPWR101

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 multi-layer 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

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.
