× 50 Watt power amplier and multiple voltage regulator

Measured in the frequency range 20 Hz to 80 kHz; at IO(reg) =10mA
12.4 Stability
The regulators are made stable by connecting capacitors to the regulator outputs. The
stability can be guaranteed with almost any output capacitor if its Electric Series
Resistance (ESR) stays below the ESR curve shown in Figure 32. If an electrolytic
capacitor is used, its behavior with temperature can cause oscillations at extremely low
temperature. Oscillation problems can be avoided by adding a 47 nF capacitor in parallel
with the electrolytic capacitor. The following example describes how to select the value of
output capacitor.
12.4.1 Example regulator 2
Regulator 2 is stabilized with an electrolytic output capacitor of 10
F which has an ESR
of 4
. At T
amb = 30 °C the capacitor value decreases to 3 F and its ESR increases to
28
which is above the maximum allowed as shown in Figure 32, and which will make
the regulator unstable. To avoid problems with stability at low temperatures, the
recommended solution is to use tantalum capacitors. Either use a tantalum capacitor of
10
F, or an electrolytic capacitor with a higher value.
