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 amounts of 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 S...
