Noise information
The noise at the output of the regulators depends on the
bandwidth of the regulators, which can be adjusted by the
output capacitors. Table 1 shows the noise figures.
Although stability is guaranteed when C
L
is higher than
10
μ
F (over temperature range) with tan (
φ
) = 1 in the
frequency range 1 to 10 kHz, however, for low noise, a
47
μ
F load capacitor is required.
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 into a current noise by
the output capacitors). When a high frequency capacitor of
220 nF with an electrolytic capacitor of 100
μ
F in parallel is
placed directly over V
P
and GND (pins of supply voltage
and ground) the noise is minimized.
