LAYOUT GUIDELINES - THERMAL DESIGN
possible, in order to minimize resistance and hence power losses.
It is also recommended that, whenever possible, the ground, input
and output power signals should be on separate planes (PCB
layers). See Figure 15 – bold traces are power traces.

Ensure that this 1µF capacitor is placed as close to the IC as
possible to minimize the effects of noise on the device.
