A voltage regulator lf33cv datasheet designed to automatically maintain a constant voltage level. In practise we consider a virtual flow of a positive particle from plus to minus. No, not from the beginning.

That minimum amount is called the dropout lf33cv datasheet. The reason for this is that presence of electrons is not enough to power a device as presence of water is not enough to move paddle wheel.

The flow of current that we get from a battery is known as direct currentor DC. In this lf33cv datasheet, something like a switched-mode power supply. The difference is dissipated lf3c3v heat. The same is with electricity. If water level in both reservoirs lf33cv datasheet the same, no water flow in our pipe can be observed and a paddle wheel stays motionless.

This dstasheet of circuits is called voltage regulator. Examples of fixed linear voltage lf33cv datasheet Let’s take a closer look at some exemplary fixed linear voltage regulator LDO 3. Then electrons will move from negative side to positive and power our device Dstasheet.


This is known as alternating currentor AC. On the other side, lf33cv datasheet of microcontrollers components are powered with 3. It doesn’t matter which one we prefer as long as we are consequent.

Please try to find information about dropout voltage in datasheet of some regulators see further. That is why I made a decision to start from circuit which as input takes almost any power source but as output generates every time 3.


Every time we want to learn lf33cv datasheet, lf33vc is faster and better lf33cv datasheet us when we can relate all new concept to something lf33cv datasheet know well from our real life experience.

To change this, lf33cv datasheet we do in a water analogy, we have to fill with electrons one lf33cv datasheet negative side of a wire while make second side scarce of electrons positive side. In other words, there is no ordered movement of fl33cv. Additionaly somewhere in a pipe a paddle wheel is mounted to make our observations easier.

Compare for example pinouts lf33cv datasheet LDO 3. At this point we can say A voltage regulator is designed to automatically maintain a constant voltage level.

For example, lf33c common regulator such as the has an output voltage of 5V, but can only maintain this if the input voltage lf33cv datasheet above about 7V. Using linear voltage regulator you have to take into accout that dataheet of them require an input voltage at least some minimum amount higher than the desired lf33cv datasheet voltage.

Imagine that on my tutorials I use 12V powers source but you have only lf33cv datasheet 9V battery. A tool we can use to make one side negative while second positive is a battery. Please pay an attention to pinouts connections and check it twice befor use if you lf33cv datasheet want to damage your regulator.

As we can see from preceding material, a real current flow direction is from negative side lf33cv datasheet to positive plus. Switching converters When the output regulated voltage must be higher than the available input voltage, no linear regulator will work.


We may preffere buck converters see further over linear regulators because they are more efficient and do not require heat sinks, but they are more expensive. So if you have 3. Imagine a pipe interconnecting lf33cv datasheet identical reservoirs filled with some amount of water.

In this tutorial we cover the following llf33cv Before we start: Our obserwation is that despite we have a conductor pipe dataasheet lf33cv datasheet inside it water which can power our device move a paddle wheels nothing happens.

This could be a problem, because all components’ values like resistance, capacity etc woud be for you datashset force lf33cv datasheet to recalculate all of them. During our tutorials we will build many circuits and we can power them with different batteries: In this type regulator lf33cv datasheet, the input current required is always the same as the output current.

As a rule of thumb we have to remember that for linear voltage regulator the input voltage must always be higher than the output voltage by some minimum amount. To move our paddle wheel, we have to generate a water flow in a pipe. Simple linear regulators may only lf33cv datasheet a Zener diode and a series resistor; more complicated regulators include separate lf33cv datasheet of voltage reference, error amplifier lf33cv datasheet power pass element. datasheeet

The flow lf33cv datasheet current that we get from the power outlet lf33cv datasheet our home is very different.

Like the flow of water from a faucet, it is a steady stream that flows in one direction. Such an analogy, when basic concepts of electricity are concerned, is a water.
