Typical Application for L7805A Reducing power dissipation with dropping resistor

Typical Application for L7805A Reducing power dissipation with dropping resistor. The L78 Series of fixed voltage regulators are designed with thermal overload protection that shuts down the circuit when subjected to an excessive power overload condition, internal short-circuit protection that limits the maximum current the circuit will pass, and output transistor safe-area compensation that reduces the output short-circuit current as the voltage across the pass transistor is increased
