The SI-3010LLS is a series regulator IC using NPN bipolar transistors for a power section. The VIN terminal is connected to the NPN bipolar transistor of a power section. The VB terminal is connected to the power supply of the control section and also to the former stage transistor in Darlington connection withthe NPN power transistor connected to the VIN terminal. By performing 2 inputs, the SI-3010LLSL is operated in the ultra hypo saturation to the VIN terminal. The ON/OFF terminal of Active High is provided to make the current consumption of circuits at OFF time zero. This is a regulator that uses low ESR capacitors like a ceramic capacitor for the output capacitor
