To make a DC voltage regulator, use a linear monolithic IC regulator. They are lightweight, inexpensive, and are able to output stable reference voltages. They are also relatively sturdy for their size. IC voltage regulators have three terminals or pins that are usually connected to capacitors i...
Avoltage regulatoris a device used to change fluctuating voltages on its input to a defined and stable one on its output. Voltage regulators may be mechanical, electric, AC, or DC. In this article, we are going to look at DC electronic linear regulators. Application of Regulators Most circui...
When testing the voltage of a voltage regulator, we first check the voltage from the input pin to ground. This is to make sure that voltage is, in fact, being supplied to the regulator. If the regulator isn't receiving sufficient voltage, of course it will not be able to output its ra...
in this case the 9-volt battery, and before the input of the LM7805 regulator. This capacitor is there to filter out any noise coming from the voltage source (the battery). The voltage regulator works best and will be most efficient when a clean DC signal is fed into it. We don'...
A popular alternative, the switching converter, alternately stores energy in an inductor’s magnetic field, and releases the energy to the load at a different voltage. Its reduced losses make it a better choice for high efficiency. Buck, or step-down converters—covered here—provide lower ...

For our case, we will use a transformer to step down the voltage, followed by a bridge rectifier to convert the AC voltage to DC. Step 3: Connect the Transformer Connect the primary winding of the transformer to the AC power source and the secondary winding to the rectifier. Make sure ...
PROBLEM TO BE SOLVED: To provide a voltage regulator for easy replacement of parts and a method for replacing parts of the voltage regulator. A voltage regulator including a series transformer (1), an adjusting transformer (2), a measuring transformer (PT1, PT2), a tap switch (3a), and...
Personally, I NEVER calculate this directly. I always do an internet search for “voltage divider calculator” and plug in the numbers. It is a good idea to run this check to make sure the circuit is properly designed. All the other capacitors and diodes are used for filtering and protectio...
Line/mains voltage is too high to be connected directly to an Arduino. The ADC cannot measure voltages that high. Some sort of pre-scaler is required to...
