Embodiment Construction
[0027] The implementation of the present invention will be described in detail below in conjunction with the accompanying drawings and examples, so as to fully understand and implement the process of how to apply technical means to solve technical problems and achieve technical effects in the present invention. It should be noted that, as long as there is no conflict, each embodiment and each feature in each embodiment of the present invention can be combined with each other, and the formed technical solutions are all within the protection scope of the present invention.
[0028] Traditional linear regulators require the input voltage to be 2v to 3v higher than the output voltage, otherwise they cannot work normally. But in some cases, such conditions are too harsh, such as 5v to 3.3v, the voltage difference between input and output is only 1.7v, which obviously does not meet the conditions. In response to this situation, an LDO power conversion chip has emerged.
