The 7812 IC is a fixed output, three terminal precision positive voltage regulator in 3 pins TO-220 package. This regulator can provide local on-card regulation by eliminating distribution problems associated with single point regulation. The fixed voltage regulator is designed with thermal overload protection that shuts down the circuit when subjected to an excessive power overload condition, internal short circuit protection that limits maximum current the circuit will pass and output transistor safe area compensation that reduces the output short circuit as the voltage across the pass transistor is increased. If adequate heat sinking is provided then this positive voltage regulator can deliver over 0.5A output current.
