n 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 COUT with good frequency characteristics and ESR (Equivalent Series Resistance) of which is 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
mV(Avg.) are marked as the hatched area in the graph.
<Test conditions>
(1) VIN=3.8V
(2) Frequency band: 10Hz to 2MHz
(3) Temperature: 25
