How does LM7812 work?
How does LM7812 work?
The ic 7812 is a positive voltage regulator which means that it generates the positive voltage with respect to the common ground. In case if both the positive and negative voltage supply is needed in the same circuit. The voltage regulator ic 7812 is combined with its corresponding 79XX family IC that is 7912 IC.
How do shunt regulators work?
The shunt regulator or shunt voltage regulator is a form of voltage regulator where the regulating element shunts the current to ground. The shunt regulator operates by maintaining a constant voltage across its terminals and it takes up the surplus current to maintain the voltage across the load.
What is the regulated output voltage of LM7812?
LM7812 IC comes in the family and provides a fixed regulated output of 12V DC for a variable input voltage range of 14.5 to 27V DC.
How do adjustable voltage regulators work?
An adjustable voltage regulator is a regulator that can be adjusted to output any voltage from the range that the voltage regulator is designed to output. Here you see we connect two resistors to the voltage regulator. These resistors determine the voltage that the voltage regulator adjusts to and outputs.
Which principle the SMPS is working?
SMPS regulator converts unregulated DC input voltage to a regulated and smooth DC output voltage at different voltage levels. So that the working of SMPS is based on the Chopper principle.

What is the theory of shunt?
In electronics, a shunt is a device that creates a low-resistance path for electric current, to allow it to pass around another point in the circuit. The origin of the term is in the verb ‘to shunt’ meaning to turn away or follow a different path.
What is shunt and its uses?
Definition: shunt is a device used to calibrate or extend the range of an ammeter. It is connected in parallel in a circuit. We know its main need is to measure current, hence it needs low resistance and to have low resistance it must be connected in parallel.
Which transistor is used in SMPS?
The buck converter is a type of switch-mode power supply that is designed to convert electrical energy from one voltage to a lower one. The buck converter operates with a series connected switching transistor. As the duty cycle, D < 1, the output voltage of the buck is always smaller than the input voltage, VIN.
