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 Output Current is varied.
For this purpose, be sure to use a capacitor COUT with good frequency characteristics and ESR (Equivalent
Series Resistance) in the range described as follows:
The relations between IOUT (Output Current) and ESR of Output Capacitor are shown below. The conditions
when the white noise level is under 40V (Avg.) are marked as the hatched area in the graph.
<Test conditions>
(1)Frequency band: 10Hz to 2MHz
(2)Temperature: 25°C
