IC 7806 Voltage regulator Pin and Circuit Explained

About 7806 Voltage regulator

7806 Voltage regulator is a type of self-contained fixed linear voltage regulator integrated circuit. The IC belongs to 78xx voltage regulator family which is commonly used as the regulated power supply in electronic circuits. The 7806 voltage regulator IC is ease-of-use and available in very low cost. The last two digits of 7806 indicates the output voltage that is voltage.

78xx voltage regulator ic

The 7806 regulator line is a positive voltage regulator that is the 7806 voltage regulator ic generate the voltage which is positive 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 7806 is combined with its corresponding 79XX family IC. The voltage regulator 7806 is available most commonly in TO-220 package, more over the IC is also available in TO-3, TO-92 and surface mount Packages.

The 7806 Voltage regulators do operate at their optimal capability if the input voltage is at least 2.5 volt greater than the output voltage and the current is 1 or 1.5 Amperes more. Though the voltage and current different is different for other IC Packages.

How to use IC 7806

78xx voltage regulator circuit

The 7806 ic have 3 pins, Pin 1 is a positive input, Pin 3 is a positive output and pin 2 is negative common ground between both input as well as output voltage. When using the voltage regulator setup, you need to take care of the current through the voltage regulator ic do not exceed beyond the capacity which is mentioned in the datasheet or else it may blow off. You also have to be careful with the connection you are making with the voltage supply. Reverse polarity does get the ic heat up really quickly, you can also use a pn junction diode in order to prevent such a condition.

You can use the capacitors in order to minimize the voltage fluctuations in the circuit and maintains the constant voltage across the input as well as output of the circuit.

Advantages

  • 7806 voltage regulator ic does not require any component to balance or saturate their output voltage.
  • The 7806 ic has a built-in protection from the high current. There is a heat-sink with the common ground connected with which is helpful in order to prevent our regulator ic from overheating and short-circuits making it uncompromising in the most application.

      You my need to use a resistor which may effect your input voltage as well..

      You may need to use another voltage regulator IC then 7806.

      If we apply current more then the IC’s capacity with the sufficient input voltage, the IC will overheat. In 7806 regulator IC the maximum current must be around 1.5A.

      for better output the input voltage must be 2V greater then the output voltage that is 8V. You can apply maximum voltage of 35V to the 7806 IC.
