What is the purpose of LM7812?
It has many uses. For instance, it is used in electronic communications, motors, LEDs, flashlights, load switches, DC fans and many others. LM7812 ICs are widely used in the larger rating motor and electrical power supply industry.
How does a 7812 work?
The ic 7812 is a positive voltage regulator which means that it generates the positive voltage with respect to the common ground. The ic 7812 Voltage regulators do operate at their optimal capability, if the input voltage is at least 2.5 volt greater than the output voltage (i.e 14.5 V min.)
What will be the output voltage 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 regulator circuit?
A voltage regulator is a circuit that creates and maintains a fixed output voltage, irrespective of changes to the input voltage or load conditions. Voltage regulators (VRs) keep the voltages from a power supply within a range that is compatible with the other electrical components.

Which of the following IC gives DC regulated output voltage?
Fixed Positive Voltage Regulator This IC regulator provides a fixed positive output voltage. Although many types of IC regulators are available, the 7800 series of IC regulators is the most popular. The last two digits in the part number indicate the d.c. output voltage.
What is the maximum voltage of an lm7812 IC?
Maximum input voltage is 35V DC Low standby current only 8mA LM7812 Description: LM7812 is a TO-220 packaged positive voltage regulator IC of LM78xx series that is manufactured by many different electronic components manufacturers.
Which is the equivalent of a lm7812 pinout?
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. LM340-12, LM340A-12 and LM1084-12 can be used as equivalent of LM7812, if these equivalent voltage regulators are not available you can also use an LM317 IC to get fixed 12V output.
Where to put the lm7812 in a heatsink?
On this project I use the LM7812 in TO-220 footprint, which can be screwed to the rear of a heatsink for better heat dissipation. You will get better heat conduction if you use thermal paste between the heatsink and LM78xx before screwed together.
What kind of power supply does a LM78xx have?
You will get better heat conduction if you use thermal paste between the heatsink and LM78xx before screwed together. The bridge rectifier is a classic 2KVV.
