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, C3 and C4 with 1.0
μF or more.
If a tantalum capacitor is used, and its ESR (Equivalent Series Resistance) of C2, C3 and C4 is large, the loop
oscillation may result. Because of this, select C2, C3 and C4 carefully considering its frequency characteristics.
PCB Layout
Make VDD and 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 1.0
μF or more between VDD and GND pin, and as
close as possible to the pins.
Set external components, especially the output capacitor C2, C3 and C4 as close as possible to the ICs, and
make wiring as short as possible.
