Linear voltage regulator, positive fixed output 5 V, output current up to 1.5 A, TO-220 package. Internal thermal overload and short-circuit protection. Widely used for local on-board regulation in industrial and embedded systems.
The LM7805 is a three-terminal positive voltage regulator delivering a fixed 5 V output at currents up to 1.5 A. It requires minimal external components and includes internal current limiting, thermal shutdown, and safe-operating-area protection, making it a robust choice for local regulation across industrial, automotive, and embedded designs.
No external trimming required, simplifying board design and reducing part count.
Enough headroom for most on-board rails without a secondary pass device.
Through-hole power package with a mounting tab for straightforward heatsinking.
Internal safeguards improve field reliability under fault conditions.
