QAPPLICATION NOTE

NJM2512 Ahas possibilities that decrease in the capacitance in low-frequency band when the ceramic capacitor is

used(pin7). It is a possibility that the sag is generated when the ceramic capacitor decreases capacity.

Please verify it in consideration of the capacity drop of the ceramic capacitor.
