DC voltage regulator is widely available on the market with features that are tailored to the usability. No voltage applications that follow generally begin 1.5V voltage up to 32V. But do not do an electronic application requires a unique voltage, such as a laptop, we come across an input voltage of 19V DC.
When a DC power adapter that we have cannot provide for the voltage, this will cause the application may not work well. This is the importance of an adjustable DC voltage regulator so that we can change the output voltage to a certain voltage magnitude.
