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 0.47
μ
F or more ceramic capacitor C
OUT
.
(Test these ICs with as same external components as ones to be used on the PCB.)
When a tantalum capacitor is used with this IC, if the equivalent series resistor (ESR) of the capacitor is large,
output voltage may be unstable.
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 as much as 1.0
μ
F capacitor between V
DD
and GND pin as close as possible.
Set external components such as an output capacitor, as close as possible to the ICs and make wiring as
short as possible.
