L7812CV Datasheet, PDF

The L7812CV is a specific model of the 7812 series, which is a linear voltage regulator IC designed to provide a fixed output voltage of +12 volts. The L in L7812CV indicates that it is a part of the L78xx series of voltage regulators. Here are some key features and specifications of the L7812CV:

Voltage Regulation: The L7812CV is designed to regulate the output voltage to a constant +12 volts, providing a stable DC voltage output.

Output Current: The maximum output current that the L7812CV can supply is typically in the range of 1A to 1.5A. The actual current capability depends on factors such as the input-output voltage differential and thermal considerations.

Input Voltage Range: The input voltage should be higher than the desired output voltage by a certain amount, known as the dropout voltage. For the L7812CV, the typical dropout voltage is around 2 volts. Therefore, the input voltage should be at least 14 volts for proper regulation.

Output Voltage Accuracy: The output voltage is accurate within a specified tolerance, usually around ±2%, ensuring a stable and precise +12V output.

Thermal Overload Protection: The L7812CV often includes internal thermal shutdown protection to prevent damage due to excessive heat. If the temperature exceeds a certain threshold, the regulator will shut down until it cools down.

Short Circuit Protection: The IC may include short circuit protection to prevent damage in case of a short circuit on the output.

Package Type: The L7812CV is commonly available in a TO-220 package, which provides good thermal performance and ease of mounting to a heatsink.

Applications: The L7812CV is widely used in various electronic circuits where a stable +12V power supply is required. It finds applications in power supplies for electronic devices, battery chargers, and other low to moderate power applications.
