L7805 VS LM259: What’s the difference?

The L7805 Voltage Regulator IC is a widely used voltage regulator that may be found in many electronic projects. For a changeable input voltage supply, it gives a constant +5V output voltage.

It is available in several IC packages, including TO-220, SOT-223, TO-263, and TO-3.

Here are the L7805 Pinout and Configurations

The LM2596 is a well-known step-down switching regulator IC. The adjustable version can accept input voltage ranging from 4.5V to 40V and convert it to variable voltage sourcing of up to 3A of continuous current. It is often used in power modules to power/control big loads due to its high current capabilities.
