ESR vs. Output Current

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, use a capacitor C
OUT
with good frequency characteristics and ESR (Equivalent Series Resistance)
of which is in the range described as follows:

Measuring Circuit for white noise; R1114xxx1B/D
The relations between I
OUT
(Output Current) and ESR of an output capacitor are shown below. The conditions
when the white noise level is under 40
μ
V (Avg.) are marked as the hatched area in the graph.
(Note: If additional ceramic capacitors are connected to the Output Pin with 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.)
