Today a friend of me visits at a house. He leads old equipment come to give very plentiful and tell beg for DC power supply 10A circuit. That be simple please , when I sees the equipment that him has had already. Then take this circuit see use 78XX integrated circuits. Have [...]

When i want dc regulator power supply 18V 1A.
I like this circuit because it is easy to make.

The main parts of the are the IC 7818 and the 1000uf 35V capacitors.
I used the 18VAC 1A transformer,The output of the transformer is rectified by diode 1N4007 or equivalent.
The voltage here is unregulated [...]

Of all the voltage regulator ICs, the 78xx family is by far the most established. Not surprisingly! It’s difficult to get performance this good with so few outside components necessary.

Just like the famous LM317, the 78xx family incorporates automatic shutdown in case of overheating. You can get up to 1.5A of current with a [...]
