Application Notes
1. External compensation capacitor
Connect the input pin and ground pin with a 3.3
μ
F capacitor and the output pin and ground pin with a 33
μ
F
capacitor in order to keep the stability of the IC in operation. Make sure that the 3.3
μ
F capacitor is as close as possible
to the input pin and ground pin 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 (equivalent series resistance) of the capacitor for the
AN80MxxRSP Series conduct a full evatuation under the right operating conditions.
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.
