TECHNICAL NOTES
When using these ICs, consider the following points:
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 capacitor C
OUT
with good frequency characteristics and ESR (Equivalent Series
Resistance) in the range described as follows:
The relations between I
OUT
(Output Current) and ESR of Output Capacitor are shown below. The conditions
when the white noise level is under 40μV (Avg.) are marked as the hatched area in the graph.
