C2, C3: Refer to the following table

1.Mounting on PCB

Connect a capacitor with a capacitance value as much as 1.0

as close as possible to the pins.

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

short as possible.

2.Phase Compensation

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

this purpose, use capacitos C2 and C3 which are shown below table “Recommended Ceramic capacitor for

output “If you use a tantalum type capacitor and ESR value of the capacitor is Iarge, output might be unstable.

Evaluate your circuit with considering frequency characteristics.
