Product Description
The L7812CV Linear Voltage Regulator IC is a reliable three-terminal positive voltage regulator designed to provide a stable 12V fixed output for a wide range of electronic circuits and power supply applications. Housed in the industry-standard TO-220AB package, the L7812CV is capable of delivering up to 1.5A output current when used with an adequate heat sink.
Featuring built-in current limiting, thermal overload protection, and safe operating area (SOA) protection, the L7812CV is designed for dependable long-term operation and enhanced circuit safety. These integrated protection features make the regulator highly resistant to damage caused by overloads or excessive temperatures.
Ideal for power supplies, embedded systems, DIY electronics, Arduino projects, industrial controls, and repair work, the L7812CV eliminates the need for complex voltage regulation circuitry while providing clean and consistent 12V DC output. Although primarily intended as a fixed-voltage regulator, it can also be combined with external components for adjustable voltage and current applications.
