What is the output of 7812 IC regulator?

The 7812 is a fixed voltage linear regulator that can output 12V at up to 1A current with an input voltage range of 14 – 35V.

What is the purpose of LM7812?

LM7812 ICs are widely used in the larger rating motor and electrical power supply industry. They are used as an independent voltage regulator of high supply voltage of electric motors. In addition, they are used in the AC motor controllers. LM7812 ICs are used in electronic security and fire alarms.

When would you use a linear voltage regulator?

Linear regulators are a great choice for powering very low powered devices or applications where the difference between the input and output is small. Even though they are easy to use, simple and cheap, a linear regulator is normally inefficient.

What does a 12V voltage regulator do?

A voltage regulator generates a fixed output voltage of a preset magnitude that remains constant regardless of changes to its input voltage or load conditions.

What is linear voltage?

Linear voltage regulators—also called LDOs or low-dropout linear regulators—use a transistor controlled by a negative-feedback circuit to produce a specified output voltage that remains stable despite variations in load current and input voltage.

What is LM7805 voltage regulator?

The LM7805 is a voltage regulator that outputs +5 volts. Like most other regulators in the market, it is a three-pin IC; input pin for accepting incoming DC voltage, ground pin for establishing ground for the regulator, and output pin that supplies the positive 5 volts.

What are the disadvantages of linear regulator?

Disadvantages of linear regulators

  • Simple.
  • Cheap.
  • Power supply rejection ratio. Linear regulators respond quickly to changes in input voltage, producing an output voltage that is mostly free of any ripple on the input.
  • Respond quickly to changes in load voltage.
  • No switching noise.

What are the advantages of using linear regulators?

Linear regulators have the advantage of very “clean” output with little noise introduced into their DC output, but they can be much less efficient than switching converters and are unable to step-up the input voltage like their switched counterparts.
