TECHNICAL NOTES

When using these ICs, consider the following points:

Phase Compensation

In these ICs, phase compensation is made for securing stable operation even if the load current is varied. For this

ries Resistance).

(Note: When the additional ceramic capacitors are connected to the Output Pin with Output capacitor for phase com-

pensation, the operation might be unstable. Because of this, test these ICs with as same external components as ones

to be used on the PCB.)

PCB Layout

sible.

Set external components, especially output capacitor as close as possible to the ICs and make wiring shortest.
