L7805CV Voltage Regulator 5V 1.5A Positive Linear Regulator TO-220

L7805CV Voltage Regulator – 5 V / 1.5 A Positive Linear Regulator (TO‑220)
The L7805CV is a classic three‑terminal linear regulator that delivers a steady 5 V output from a wide range of input voltages (7 V‑35 V). Packaged in a rugged TO‑220 case, it’s ideal for powering microcontroller boards, sensors, and low‑power digital circuits in hobby projects, lab prototypes, and classroom labs. Its built‑in current limiting and thermal overload protection make it a dependable “plug‑and‑play” solution for anyone needing a reliable power source without the complexity of switching regulators.

What students will learn: Using the L7805CV introduces learners to core concepts of power management—voltage regulation, heat dissipation, and protection mechanisms. Students will gain hands‑on experience designing bias networks, calculating dropout voltage, and implementing proper heat‑sink sizing, while seeing how a single component can transform an unstable supply into a clean 5 V rail for Arduino, Raspberry Pi‑Zero, or sensor arrays.

Key features

• Fixed 5 V output with 1.5 A continuous current capability
• Wide input range (7 V‑35 V) and low dropout (≈2 V) for flexible designs
• Integrated short‑circuit, over‑current, and thermal shutdown protection
• TO‑220 package with exposed metal tab for easy heat‑sink attachment
• Low output noise and ripple—perfect for analog and digital circuitry

Why it’s great: The L7805CV’s reputation for simplicity, robustness, and affordability makes it a staple in every electronics toolkit. Its no‑frills design requires only two external capacitors to achieve a stable output, saving board space and design time. Whether you’re building a robotics controller, a portable sensor node, or a classroom demonstration kit, the L7805CV delivers dependable 5 V power that lets students focus on learning the fundamentals rather than troubleshooting complex power‑supply issues.
