Embodiment Construction

[0019] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0020] The embodiment of the invention discloses an adjustable voltage stabilizing circuit, which expands the adjustable range of the output voltage by setting a voltage follower circuit, a current buffer circuit and a voltage stabilizing source circuit. The voltage follower circuit and the current buffer circuit convert the voltage source signal into a constant current source signal, and then adjust the output of the adjustable voltage stabilizing circuit through the voltage stabilizing source circuit. The adjustable voltage stabilizing circuit can be adapted to more circuits.

Abstract

The invention relates to an adjustable voltage-stabilizing circuit, and the circuit comprises a voltage following circuit, wherein the input end of the voltage following circuit is connected with an external power source, the output end is connected with a current buffering circuit, and the voltage following circuit is used for amplifying a current of a voltage source signal; the current bufferingcircuit, wherein the output end of the current buffering circuit is connected with a voltage-stabilizing source circuit, and the current buffering circuit is used for converting the voltage source signal with the amplified current into a constant current source signal; the voltage-stabilizing source circuit, wherein the output end of the voltage-stabilizing source circuit is connected with an external load and is used for adjusting the output voltage of the adjustable voltage-stabilizing circuit. The circuit provided by the invention can enable the range of the output voltage of the circuit to be adjusted in a larger range, increases the maximum output voltage, and can be enabled to meet more voltage demands.

Description

technical field [0001] The invention relates to the technical field of power supply voltage stabilization adjustment, in particular to an adjustable voltage stabilization circuit. Background technique [0002] With the development of science and technology, electronic devices in various application scenarios have gradually and rapidly entered people's lives. In the circuit design of electronic equipment, reference voltage regulators involving AD sampling, comparators and other circuits are widely used. In order to apply voltages in various scenarios, adjustable precision reference voltage regulators have also emerged as the times require. [0003] In the current traditional technology, the voltage adjustment range of the adjustable precision reference voltage regulator can only reach 36V at the highest. However, in the battery power industry, more and more high-voltage batteries are starting to be widely used. For example, in the automotive industry, in addition to the tra...
