L7805CV
Classic 3-terminal 5V linear voltage regulator with 1.5A output current and thermal/overload protection.
Product Overview
Description
The L7805CV is a classic three-terminal positive voltage regulator providing a fixed 5V output with up to 1.5A output current.
This regulator features internal current limiting, thermal shutdown, and safe operating area protection, making it virtually indestructible under normal operating conditions.
The L7805 requires only two external capacitors for operation, making it one of the simplest solutions for creating a stable 5V supply from a higher voltage source.
With its TO-220 package and robust protection features, the L7805 has been the go-to solution for 5V power supplies for decades.
