What is the use of IC 7809?
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.
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.
What does a voltage regulator IC do?
A voltage regulator is an integrated circuit (IC) that provides a constant fixed output voltage regardless of a change in the load or input voltage. It can do this many ways depending on the topology of the circuit within, but for the purpose of keeping this project basic, we will mainly focus on the linear regulator.
What is the application of 7805 IC?
Application areas for 7805 IC Fixed-Output Regulator. Positive voltage Regulator in Negative voltage Configuration. Adjustable Output Regulator. Current Regulator.
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.
How does a step up voltage regulator work?
This 5 V boost (step-up) voltage regulator generates higher output voltages from input voltages as low as 0.5 V, and it also automatically switches to a linear down-regulation mode when the input voltage exceeds the output.
How does a step down voltage regulator work?
A step down converter—also known as a buck converter—converts high voltage to low voltage, usually transforming AC current to DC current. A voltage regulator maintains a constant output voltage for a circuit, regardless of any changes in connected devices or electrical load.
How does IC 7805 works?
IC 7805 is a 5V Voltage Regulator that restricts the output voltage to 5V output for various ranges of input voltage. It acts as an excellent component against input voltage fluctuations for circuits, and adds an additional safety to your circuitry. It is inexpensive, easily available and very much commonly used.
