Description

[0001] technical field [0002] The invention belongs to a voltage stabilizing circuit, in particular to a series voltage stabilizing circuit used in a low-power power supply circuit. [0003] Background technique [0004] A voltage stabilizing circuit is a circuit that can maintain a constant output voltage when the input voltage, load, ambient temperature, circuit parameters, etc. change. This circuit can provide a stable DC power supply and is widely used in various electronic devices. [0005] Various voltage stabilizing circuits can be seen everywhere in the prior art, but most of them have complex structures, complete functions, and relatively expensive prices. The instability of the quality, and in many occasions, the functional requirements for the voltage stabilizing circuit are relatively low, as long as it meets a single voltage stabilizing function. [0006] Contents of the invention [0007] In order to overcome the deficiencies of the prior art, the objec...
