Output switching regulator circuit for computer usb3.0 interface

Abstract

The invention discloses an output switch voltage stabilizing circuit for a computer USB3.0 interface. The output switch voltage stabilizing circuit comprises a first resistor, a second resistor, a third resistor, a fourth resistor, a fifth resistor, a sixth resistor, a seventh resistor, a first capacitor, a second capacitor, a third capacitor, a diode, a triode, an inductor and a voltage regulator, wherein the first end of the first resistor is connected with the collector electrode of the triode and the input end of the voltage regulator. According to the output switch voltage stabilizing circuit for the computer USB3.0 interface, input voltage is regulated and processed by the voltage regulator and then is loaded to the base electrode of the triode by the voltage control terminal of the voltage regulator; after outputting current, the collector electrode of the triode outputs stable current together with the voltage regulator via the inductor. The output switch voltage stabilizing circuit is simple in structure, can stably output 1V current and has popularization and use values.
