Question:
Can we use any capacitor other than a tantalum electrolytic capacitor as the output capacitor of the IC
Answer:
If a ceramic capacitor or OS capacitor that has a low ESR is used, the output of the IC is likely to
produce oscillation.
To ensure stable operation of the S-816 Series, a capacitor having an appropriate ESR (Equivalent
Series Resistance) range must be used.
If the ESR of a capacitor deviates from that range, the output of the regulator will become unstable,
which may cause oscillation.
For this reason, the use of tantalum electrolytic capacitors is recommended.
If a ceramic capacitor or OS capacitor is to be used, an additional resistance will have to be added in
series with the output capacitor instead of the ESR. The resistance value to be added ranges from 0.1
to 5
. Since said value depends on the service conditions, the value should be set only after a
thorough evaluation is performed. In general, a resistance of approximately 0.3
is recommended.
If an aluminum electrolytic capacitor is to be used, exercise extreme care, as its ESR tends to increase
at low temperatures, resulting in oscillation. Conduct an adequate evaluation in advance, including the
temperature characteristics of the capacitor.
