The Voltage ranges 5V and 12V are widely used in all kinds of simple electronic circuits, so its meaningful to learn this simple construction. A: As an example, we'll use the popular voltage regulator, the LM Below is the pinout of the LM voltage regulator.
The input voltage that needs to be regulated down goes into pin 1 Input. The ground pin is pin 2. And the regulated output voltage comes out from pin 3 Output. A: In most of our electronic products or projects we need a power supply for converting mains AC voltage to a regulated DC voltage.
For making a power supply designing of each and every component is essential. A: 5v volt regulator circuit which can be made from only three components, its simple, cheap and easy way to get a current up to 1A and a voltage of more than 5v can only be regulated by this circuit, this circuit can be used as a bread board power supply.
A: Depending on the voltage regulator in use, we can get a regulated positive or negative voltage, at whichever voltage we want. The LM78XX voltage regulators are a popular kind for regulating and outputting positive voltage, while the LM79XX are a popular series of regulators for negative voltage. In this article, we use a positive voltage regulator, which outputs 5V, the LM regulator. A: Use the values that are suggested in the datasheet.
If you add capacitors a factor of 10 smaller called decade capacitors it will help with higher frequency noise RF, or radio band noise , as an effects of the impedance of a capacitor. When someone increases this they are allowing their circuit to pull power from the power source for longer.
If you have a long power line this will act as a small tank of power. If you are going to have long power lines, or very inductive power lines, add this.
