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 40 V (Avg.) are marked as the hatched area in the graph.
<Test conditions>
(1) Frequency band: 10Hz to 2MHz
(2) Temperature: 25 C
