Linear regulator
In electronics, a linear regulator is a system used to maintain a steady voltage. The resistance of the regulator varies in accordance with the load resulting in a constant output voltage. The regulating device is made to act like a variable resistor, continuously adjusting a voltage divider network to maintain a constant output voltage and continually dissipating the difference between the ...
THE POWER SUPPLY Talking Electronics
TESTING A POWER SUPPLY One of the most difficult things to do is test the maximum current capability of a power supply. The easiest thing to do is to connect it to a project and see if it operates correctly, but of you are designing a power supply for general use, you will need to know its capabilities.
Variable Voltage Power Supply Using The LM317TBasic ...
Then whatever current flows through resistor R1 also flows through resistor R2 (ignoring the very small adjustment terminal current), with the sum of the voltage drops across R1 and R2 being equal to the output voltage, Vout.Obviously the input voltage, Vin must be at least 2.5 volts greater than the required output voltage to power the regulator. Also, the LM317T has very good load regulation ...

RECTIFYING a Voltage These circuits show how to change an oscillating voltage (commonly called AC) to DC. The term AC means Alternating Current but it really means Alternating Voltage as the rising and falling voltage produces an increasing and decreasing current.
