Application information
NOISE
The noise at the output of the regulator depends on the
bandwidth of the regulator, which can be adjusted by
means of the output capacitor. In Table 1 the noise figures
are given.
Table 1
Noise gures
Note
1. Measured at a bandwidth of 10 Hz to 100 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 regulator is translated into a current noise by
means of the output capacitor). When a high frequency
capacitor of 220 nF in parallel with an electrolytic capacitor

F is connected directly to pins 17 and 7 (supply
and ground) the noise is minimized.
STABILITY
The regulator is stabilized by means of the output
capacitor. The value of the output capacitor can be
selected using the diagram shown in Fig.6. The following
two examples show the effects of the stabilization circuit
using different values for the output capacitor.
Example 1
The regulator is stabilized using an electrolytic output
capacitor of 68
F (ESR = 0.5 ). At 40 °C the capacitor
value is decreased to 22
F and the ESR is increased to
3.5
. The regulator will remain stable at a temperature of
40 °C.
Example 2
The regulator is stabilized using an electrolytic output
capacitor of 10
F (ESR = 3.3 ). At 40 °C the capacitor
value is decreased to 3
F and the ESR is increased to
23.1
. The regulator will be instable at a temperature of
40 °C. This can be solved using a tantalum capacitor of
10
F.
