*4: SI-3010KM, SI-3050KM and SI-3090KM, SI-3120KM cannot be used in the following applications because the built-in foldback-type overcurrent protection may cause errors during
start-up stage.
(1) Constant current load (2) Positive and negative power supply (3) Series-connected power supply (4) VO adjustment by raising ground voltage
*5: VIN (max) and IO (max) are restricted by the relation PD = (VIN - VO) × IO. Please calculate these values referring to the Copper Laminate Area vs. Power Dissipation data as shown
hereinafter.

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