LM7805 7805 Voltage Regulator 5V Voltage Regulator

Description

The LM7805 (7805) is a classic 3-terminal positive voltage regulator that provides a stable +5V output with  maximum 1.5A current capacity, featuring built-in thermal shutdown, short-circuit protection, and safe operating area protection. It remains widely used in electronics for powering microcontrollers, sensors, and logic circuits, though future designs increasingly shift toward modern low-dropout (LDO) and switching regulators for efficiency.
