What is 7809 IC?

7809 IC is a simple voltage regulator IC which regulates the voltage to 9v, which means it gives a fixed 9V regulated voltage. It is a monolithic 3 terminal regulator IC. Its 9v output voltage makes is most convenient to use in TTL devices or circuits. It is a member of 78xx series fixed linear voltage IC.

How much power does a voltage regulator use?

the voltage regulator you are talking about can provide up to 500mA @ 5V. this regulator will always provide 5V. how much current is drawn from it depends what you are connecting to it. the maximum load of the regulator is 500mA but it is perfectly acceptable to draw less from it.

What is 7809 IC and what will be the output of 7809 IC?

The name 7809 signifies two meanings, “78” means that it is a positive voltage regulator and “09” means that it provides 09V as output. The output current of this IC can go up to 1.5A. But the IC suffers from heavy heat loss hence a Heat sink is recommended for projects that consume more current.

What is the nominal output voltage for IC voltage regulator 7809?

9V
LM7809 Description LM7809 is a fixed positive voltage regulator IC that is designed for a wide range of applications. The IC provides fixed 9V output with 1A to 1.5A. To achieve a fixed and stable output voltage of 9V and 1.5 amperes the input voltage should be 11V and 2 amperes.

Do voltage regulators draw current?

You’re using a linear regulator which simply “burns off” the excess voltage. The current does not change and remains the same so you can draw up to 1.25 A at the output of the regulator. So after the regulator you’re limited to 5 V, 1.25 A so 6.25 W.

Do voltage regulators reduce current?

The voltage regulator monitors the current drawn by the load and increases or decreases the voltage accordingly to keep the voltage level constant. A power supply that incorporates a voltage regulator is called a regulated power supply.

What is the current rating of voltage regulator IC lm338k?

Here is the LM338 Adjustable DC power supply circuit, 1.2V to 30V. It can provide a current maximum to 5A and 10A.

What is the current rating of voltage regulator IC LM317L?

1.2 V to 37 V
The LM317L is an adjustable 3−terminal positive voltage regulator capable of supplying in excess of 100 mA over an output voltage range of 1.2 V to 37 V.

How does a 7812 voltage regulator work?

The 7812 is a commonly used linear regulator. Input voltage can range from 14 – 35VDC and it outputs a fixed 12V at over 1A of current and up to 2.2A of surge current. For basic operation, no external components are required. Just hook up the input voltage and ground and you have 5V available on the output.

What is the output voltage of a 7809 IC?

They provide a constant output voltage for a varied input voltage. The name 7809 signifies two meanings, “78” means that it is a positive voltage regulator and “09” means that it provides 09V as output. The output current of this IC can go up to 1.5A.

So here is a really powerful 12 Volt regulator using IC 7812 which can deliver upto 15 Amperes of current. The 7812 regulator is used to maintain output at 12 volts and three TIP 2599 transistors are used to boost current. This is a costly circuit because of the high power components used.

What is the output voltage of LM317?

Well, this is a collection of voltage regulator circuits using the LM317 IC – which is an adjustable voltage regulator. LM317 is a three terminal adjustable regulator from National semiconductors and it’s input can range up to 40 volts. The output voltage can be adjusted from 1.2 V to 37 V.

What is an l7809 voltage regulator?

The L7809 voltage regulator provides 9V Positive voltage as output and can provide local on-card regulation, eliminating the distribution problems associated with single-point regulation. Although designed primarily as a fixed voltage regulator, but it can be used with external components to obtain adjustable voltage.
