Embodiment Construction

[0028] In order to make the above and other purposes, features, and advantages of the present invention more comprehensible, the preferred embodiments are specifically listed below, together with the accompanying drawings, and are described in detail as follows:

[0029] Fig. 1 is a schematic diagram of the adjusting device of the present invention. The adjusting device 100 includes a low dropout regulator (Low DropOut; LDO) 110 and a control unit 120 . The control unit 120 is used to prevent the LDO voltage regulator 110 from generating excessive surge current. The LDO regulator 110 includes an operational amplifier 111 , an output stage 112 and a voltage dividing module 113 .

[0030] Operational amplifier 111 can pass the input voltage V IN , to perform related processing (such as performing zoom-in processing). As shown, the inverting input terminal of the operational amplifier 111 receives the reference voltage V REF , whose non-inverting input terminal receives the f...

Abstract

The invention provides an adjustment device which comprises a low dropout regulator and a control unit, wherein the low dropout regulator is composed of a calculation amplifier, an output level and a partial voltage module. The calculation amplifier is provided with a non-inverting input end, an inverting input end and an output end. The output level is coupled with the output end to provide an output signal. A feedback signal given to the non-inverting input end is generated by the partial voltage module according to the output signal. The control unit is used for avoiding the voltage of theoutput end being less than a default value.

Description

technical field [0001] The invention relates to an adjustment device, in particular to an adjustment device with a control unit. Background technique [0002] With the multi-components of portable electronic products, more and more portable electronic products can use computers as transmission interfaces. For example, electronic products can be charged by using a computer's Universal Serial Bus (USB). However, when the electronic product wants to perform related actions through the USB port of the computer, there are two points that need to be paid special attention to. [0003] The first point is the inrush current. When an electronic product is plugged into a USB port of a computer, a momentary inrush current may damage an integrated circuit (IC) inside the computer. In the long run, it may cause damage to the components inside the computer. Therefore, when an electronic product is connected to a computer USB port, it is necessary to prevent excessive surge current fro...
