Description
LM7812 is a TO-220 packaged positive voltage regulator IC of LM78xx series that is manufactured by many different electronic components manufacturers. The IC provides fixed 12V output voltage no matter if the input voltage is fluctuating or changing continuously or it is higher than 12V but the input voltage should not be more than 35V which is the maximum input voltage limit this IC is capable to handle. Moreover the input voltage should not be less than 14V that is the minimum input voltage requirement of the IC to provide fixed 12V output. Although this IC is designed for fixed output but the output can also be adjusted if required by the user with the help of only two external resistors at the output the details can be found below in this article.
The schematic below shows a 12V DC power supply circuit using 7812 IC.
During usage when the IC performing voltage regulation or stepping down the input voltage all the voltage difference between the input voltage and the output is converted to heat due to which a suitable heatsink is mandatory for proper working of the IC. The IC can handle maximum load of 1A to 1.5A but the input current should be 2A to get 1A to 1.5A at the output.
