Description :

Voltage regulators are very common in electronic circuits. They provide a constant output voltage for a varied input voltage. In our case the 7805 IC is an iconic regulator IC that finds its application in most of the projects. The name 7805 signifies two meaning, “78” means that it is a positive voltage regulator and “12” means that it provides 12V as output. So our 7812 will provide a +12V output voltage. 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. 

Features of 7812 voltage Regulator :

• 12V Positive Voltage Regulator

• Minimum Input Voltage is 14.5V

• Maximum Input Voltage is 30V

• Operating current(IQ) is 5mA     

• Internal Thermal Overload and Short circuit current limiting protection is available.

• Junction Temperature maximum 125 degree Celsius

• Available in TO-220 and KTE package

Applications of 7812 voltage Regulator:

• Constant +12V output regulator to power microcontrollers and sensors in most of the projects

• Adjustable Output Regulator

• Current Limiter for certain applications

• Regulated Dual Supply

• Output Polarity-Reversal-Protection Circuit
