SI-3025LSA
Package:SOP8
The SI-3000LSA 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 electrolytic capacitors for the output capacitor at the voltage of 16V.
