The SI-3000KS is a series regulator IC using a hypo saturation type PNP bipolar transistor in the power section and it can be used with the low difference of input/output voltages. It is provided with an ON / OFF terminal which operates in Active High mode and the current consumption of circuits at OFF time is zero.It is a regulator which can use low ESR capacitors such as ceramic capacitors for the output capacitor at the voltage of 17V.
