Application Notes
1. External compensation capacitor
Connect the input pin and ground pin with a 100
μ
F capacitor
and the output pin and ground pin with a 0.1
μ
F capacitor in order
to keep the stability of the IC in operation. Make sure that the 10
μ
F capacitor is as close to the input pin and ground pin as possible
while the 33
μ
F capacitor is as close to the output pin and ground
pin as possible.
As the stability is affected by the parasitic capacitance and
impedance of the PCB pattern, pay utmost attention to the PCB
layout.
Select each capacitor in consideration of the ESR (equiva-
lent series resistance) of the capacitor for the AN80PxxRSP Se-
ries, conduct a ful evaluation under the right operating condi-
tions.
The ESR of an aluminum or tantalum electrolytic capacitor
may increase at low temperatures. Therefore, it is recommended
to connect a 0.1
μ
F to 0.47
μ
F capacitor with low internal
impedance, such as a multi-layer ceramic capacitor, in parallel to
each capacitor.
