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) of which is 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 40
