The IC belongs to 78xx voltage regulator family which is commonly used as the regulated power supply in electronic circuits. The voltage regulator IC is ease-of-use and available in very low cost. The last two digits of indicates the output voltage that is voltage. The regulator line is a positive voltage regulator that is the 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 is combined with its corresponding 79XX family IC. The Voltage regulators do operate at their optimal capability if the input voltage is at least 2.
Though the voltage and current different is different for other IC Packages. How to use IC The 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 voltage regulator ic does not require any component to balance or saturate their output voltage.
The 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.
