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 C
OUT
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
DD
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 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.
