Problems solved by technology

[0004] However, although the parallel capacitor improves the stability of the voltage regulating device, when the voltage regulating device receives the power supply voltage, an unexpected operating voltage is generated in the output signal, that is, a surge occurs.
If this surge is transmitted to the chip in the electronic product, it may cause the operation of the electronic product to fail to meet the specifications and produce unpredictable negative effects. This is not the function that the electronic product was designed to achieve

The voltage adjusting chip is provided with an enabling end, an input end and an output end, wherein the input end is used for receiving an input voltage, and the enabling end is used for receiving an enabling signal so as to enable the output end to output an output voltage. The first end of the first capacitor is coupled to the enabling end, and the second end of the first capacitor is coupled to an earthing end. The first resistor is connected in parallel with the first capacitor. The first end of the second resistor is coupled to the enabling end, and the second end thereof receives the input voltage. The first end of the second capacitor is coupled to the second end of the second resistor, and the second end thereof is coupled to the earthing end.

Description

technical field [0001] The present invention relates to a voltage regulating device, and in particular to a voltage regulating device for eliminating output voltage surges. Background technique [0002] Generally speaking, electronic products are composed of many chips with different functions. According to the circuit design, the operating voltage of these chips may not be the same as the power supply voltage of electronic products, so that electronic products must generate different voltages through voltage adjustment devices. The operating voltage of the power supply voltage is used to provide the operating voltage to these chips so that the electronic products can operate normally. [0003] Similarly, the voltage regulator also generates an operating voltage different from the power supply voltage through an internal chip, and the chip generates the operating voltage only after receiving the enable signal. As far as the voltage regulating device is concerned, when recei...
