C2, C3: Refer to the following table
1.Mounting on PCB
Make V

and GND lines sufficient. If their impedance is high, noise pickup or unstable operation may result.
Connect a capacitor with a capacitance value as much as 1.0
μ
F or more as C1 between V
DD
and GND pin, and
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.
