Note 3:
The SOIC package used is thermally enhanced through the use of a fused integral leadframe. 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.)
The hysteresis defines the maximum level of acceptable disturbance on VCC during switching. It is recommended that the VCC source
impedance be kept below 0.25Ω 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.
Ground pin current consists of controller current (0.15mA) and regulator current if enabled. The controller always draws 0.15mA from
either VCC 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.
