What is the use of IC 7809?
Brief Description of 7809 Voltage Regulator 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.
What will be output of 7809 IC?
The 7809 is a fixed voltage linear regulator that can output 9V at up to 1A current with an input voltage range of 11 – 35V.

How do you convert 12V to 9V?
To reduce a 12V circuit to 9V, place two resistors in series within the circuit. Find the difference between the two voltages (12V – 9V = 3V) to determine the total amount of resistance needed.
What is the maximum regulated output voltage of IC 7809?
The 7809 voltage regulator is a linear regulator. It can convert an input voltage of between 11V to 35V of DC power supply. Also, note that the L7809 voltage regulator will produce a fixed output of 9V at a current of 1A. Additionally, it can deliver a surge current of up to 2.2A.
How do you create a negative voltage?
A common way to generate a negative voltage has been to use an operational amplifier (op amp) to invert the output of a positive precision voltage reference. This approach typically requires a positive reference, the op amp, and two supply rails to generate the negative output.
What happens if you plug a 12V into a 9V?
Using a 12V adapter on a pedal designed to only handle 9V can completely destroy it. There are some guitar pedals built to handle voltages higher than 9V. Those pedals will work perfectly fine with a 12V adapter.
How does a 7812 voltage regulator work?
7812 is a voltage regulator IC that provides 12 v output when an input voltage of 14 v – 35 v is provided. The DC input is applied to pin number 1 and 2 and the output DC voltage is obtained from pin 2 and 3. Where pin 2 is common for negative terminal as shown in circuit diagram.
Can DC voltage negative?
An easy check to do if you have a multimeter is to take the multimeter and measure the DC voltage. Place the positive probe of the multimeter on the negative voltage and the negative probe of the multimeter on ground. If the multimeter reads voltage with a minus sign in front of it, it is negative voltage.
Can I use 12V DC instead of 9V DC?
Using a 12V adapter on a pedal designed to only handle 9V can completely destroy it. There are some guitar pedals built to handle voltages higher than 9V.
