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 1.0µF or more capacitance 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 in the typical
characteristics above. The conditions when the white noise level is under 40µV (Avg.) are marked as the
hatched area in the graph.
Test these ICs with as same external components as ones to be used on the PCB.
⋅ Make VDD and GND lines sufficient. When their impedance is high, the noise pick-up or incorrect operation may
result.
⋅ Connect the capacitor with a capacitance of 1µF or more between VDD and GND as close as possible.
⋅ Set external components, especially Output Capacitor, as close as possible to the ICs and make wiring as
short as possible.
