Noise figures
Note
1.
Measured at a bandwidth of 200 kHz.
The noise on the supply line depends on the value of the
supply capacitor and is caused by a current noise (output
noise of the regulators is translated to a current noise by
means of the output capacitors). The noise is minimum

TABILITY
The regulators are stabilized with the externally connected
output capacitors. The value of the output capacitors can
be selected by referring to the graph illustrated in Fig.7.
When an electrolytic capacitor is used, its temperature
behaviour can cause oscillations at temperatures lower
than
20
°
C. In this case, use a tantalum capacitor.
The two examples on the next page show how an output
capacitor value is selected.
