CIN: Input capacitor (22 F or larger) CO: Output capacitor *1: SI-3012KM/3025KM/3033KM (22 F or larger) It comes with a circuit configuration that uses a low ESR capacitor for the output capacitor. If an electrolytic capacitor is used, oscillation may occur at a low temperature. SI-3010KM/3050KM/3090KM/3120KM (47 F or larger) If a low ESR capacitor is used, oscillation may occur. *2: D1: Reverse bias protection diode This diode is required for protection against reverse biasing between the input and output. (Sanken SJPL-H2 is recommended.) This diode is not required at VO 3.3 V.
R1, R2: Output voltage setting resistors Output voltage can be set by connecting R1 and R2 as shown above. R2: 10 k is recommended (24 k for SI-3012KM).
R1=(VO-VADJ)/(VADJ/R2)
*3: For SI-3010KM, insert R3 in case of setting VO to VO 1.5V. Recommended value for R3 is 10k.
