DIY A variable voltage regulator based on LM317

In this article, I will gradually show you how to build your own LM317-based variable voltage regulator. Can convert 230VAC power supply Hardware components: Adjustable output linear regulator × 1 Capacitor 1000 μF × 1 Crocodile clip × 1 Rotate potentiometer, 50 kohm × 1 2.5K ohm × 1 They will learn how to make the LM317-based variable voltage regulator circuit module. Therefore, you will think of an obvious problem, what is a variable voltage regulator circuit? The circuit that adjusts the voltage in the range of 5V to 24V DC is called a variable voltage regulator relative to a constant input voltage. Sometimes, for different types of applications, we need different voltage levels, such as sometimes 5V DC, for the motor, require 9V or 12V. Therefore, we need different rated power to complete our work, or if we can only use a power unit for all types of voltage levels, what should I do? Yes, use the variable voltage regulator to be implemented, it can adjust the voltage of 1.25V to 35V. By using the LM317 regulator IC, the regulator circuit is easily established based on our own basis. In this article, I will gradually show you how to build your own LM317-based variable voltage regulator. 230VAC power can be converted to 1.25V to 24V DC.
