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 C
OUT
with good frequency characteristics and ESR (Equivalent Series Resistance)
of which is 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 40μV (Avg.) are marked as the hatched area in the graph.
< Test conditions>
(1) V
IN
= 3.8V
(2) Frequency band: 10Hz to 2MHz
(3) Temperature: 25°C
