A tantalum type capacitor is recommended. Moreover, to secure stable operation of the S-1131 Series,
it is necessary to employ a capacitor with an ESR within an optimum range (0.5 to 5 Ω). Using a
capacitor whose ESR is outside the optimum range (approximately 0.5 to 5 Ω), whether larger or
smaller, may cause an unstable output, resulting in oscillation. Perform sufficient evaluation under the
