7805 IC is a fixed output, three terminal precision positive voltage regulator in 3 pins TO-220 package. The L78M05CV 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.
