Abstract

The invention discloses a voltage regulator circuit. The circuit comprises an NMOS (N-channel Metal Oxide Semiconductor) transistor, an NPN bipolar transistor, a first resistor, a second resistor, an adjustable resistor and a schottky barrier diode, wherein the base of the NPN bipolar transistor is connected to a voltage source through the first resistor and connected to ground through the adjustable resistor, the source of the NPN bipolar transistor is grounded, and the collector of the NPN bipolar transistor is connected to the cathode end of the schottky barrier diode and the gate of the NMOS transistor and further connected to the voltage source through the second resistor; the anode end of the schottky barrier diode is grounded; the source of the NMOS transistor is grounded, while the drain of the same serves as the cathode of an output end. The voltage regulator circuit is small in volume, low in power consumption, high in speed, applicable to integration and simple in circuit structure.

Description

technical field [0001] The invention relates to a voltage regulating circuit. Background technique [0002] The voltage regulator is a circuit module often used in the circuit, which is used to adjust the function voltage of the circuit. Thyristors are generally used as voltage regulating parts in existing circuits, but the thyristors have a large area, generate large heat, and consume large power, so they are not suitable for integrated circuits at all. Generally, a voltage regulating circuit is connected outside the chip. Contents of the invention [0003] The object of the present invention is to provide a voltage regulating circuit with a MOS structure in view of the above existing problems. [0004] The technical scheme adopted by the present invention is as follows: a voltage regulating circuit of the present invention, which circuit includes an NMOS transistor, an NPN bipolar transistor, a first resistor, a second resistor, an adjustable resistor and a Schottky bar...
