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, be sure to use a 0.1
F or more capacitor C2 (Ceramic type).
If a tantalum capacitor is used, and its ESR (Equivalent Series Resistance) of C2 is large, the loop
oscillation may result. Because of this, select C2 carefully considering its frequency characteristics.
Mounting on Board
Make VDD and GND lines sufficient. If their impedance is high, pick-up the noise or unstable operation may
result.
Connect the capacitor C1 with a 0.1F or more between VDD and GND as close as possible.
Set external components, especially the output capacitor C2, as close as possible to the ICs and make
wiring as short as possible. (Refer to the typical application)
