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 2.2μF or more capacitance C
OUT
with good frequency characteristics and ESR (Equivalent Se-
ries 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.
(Note: When a ceramic capacitor is connected to the Output Pin as Output capacitor for phase compensation, the op-
eration might be unstable unless as much as 1
resistor is connected between the capacitor and GND instead of ESR.
Test these ICs with as same external components as ones to be used on the PCB.)
