C1=Ceramic 0.1µF

C2=Ceramic 0.1µF

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 purpose, use a capacitor C2 with good frequency characteristics and ESR (Equivalent Series Resistance).

(Note: If additional ceramic capacitors are connected with parallel to the output pin with an output capacitor for

phase compensation, 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

Make V^DDand GND lines sufficient. If their impedance is high, noise pickup or unstable operation may result.

Connect a capacitor C1 with a capacitance value as much as 0.1µF or more between V^DDand GND pin, and as

close as possible to the pins.

Set external components, especially the output capacitor C2, as close as possible to the ICs, and make wiring

as short as possible.
