NOTE : Applications Hints
The output capacitor has a direct influence on output voltage stability. A 10 µF capacitor will provide satisfactory results. There is no upper limit
on this capacitor value.
If necessary, this value can be reduced down to 1 µF ; however, in such case, it should be checked that output capacitor keeps sufficiently high
capacitance and low equivalent series resistance in the whole temperature range.
Such low capacitor value is not recommended either, if output current is to switch abruptly from very high to very low values (for instance, 400
mA to < 1 mA).
