Budget: the first thing is to determine how much money you want to spend on your adjustable power supply, since this way you can go to a specific range of models and eliminate everything that is out of your possibilities. NeedsThe next thing is to determine what you are going to use your dimmable power supply for, if it is for occasional maker …
power supply
I suggest you look at the datasheet for the LM324 which is a so-called single-supply op-amp, so-called because the output swings close to the negative supply (with a load to the negative supply) and the input common mode range includes the negative supply. There are many examples of circuits operating from single supplies in …
What is an Adjustable Voltage Regulator? How can it be adjusted?
OUT is the regulators'' output terminal. This is where you''ll connect your regulated power supply so that it delivers power at a consistent voltage level. IN is the part where you''ll connect your unregulated power supply—this will act as the source of power for your adjustable voltage regulator. Setting Up an Adjustable Voltage Regulator
Why do engineers usually short ground and negative ports on a DC power ...
Short answer: it can prevent damage to the power supply equipment.; Long answer: When its not shorted it means that the power supply is "floating" (i.e. NONE of the terminals is connected to ground) --> thus, although a specified voltage is maintained b/w the +ve and –ve terminals BUT the voltage b/w either +ve and ground OR –ve and …

How to Build a DC Power Supply
It can be used to produce adjustable DC voltages. So instead of using a plethora of batteries for a circuit or wall warts, switching out batteries to get the precise voltage, you can simply use a DC power supply, which greatly simplifies providing DC power to a circuit. So in order to build a DC power supply, we will need the following components:
