R1162x
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, 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 40
μ
V (Avg.) are marked as the hatched area in the graph.
