L7912CV Datasheet, PDF

The L7912CV is a linear voltage regulator IC manufactured by STMicroelectronics. It is a member of the L79xx series, which includes negative voltage regulators. The L7912CV specifically is a negative voltage regulator with an output voltage of -12 volts.

Here are some key features and specifications of the L7912CV:

Voltage Regulation: The L7912CV is designed to regulate input voltages down to -12 volts, providing a stable and fixed output voltage.

Output Current: It can typically provide a continuous output current of up to 1.5 amps, making it suitable for powering various electronic circuits and loads within its current rating.

Dropout Voltage: The dropout voltage of the L7912CV is typically around 2 volts. This means that the input voltage must be at least 2 volts higher than the desired output voltage for the regulator to operate correctly.

Thermal Protection: The IC includes built-in thermal shutdown protection to prevent damage from excessive temperatures. It shuts down the regulator temporarily if the temperature exceeds the specified limit, protecting the device from overheating.

Package Type: The L7912CV comes in a TO-220 package, which is a widely used package type for voltage regulators. This package offers good thermal performance and ease of mounting on a heatsink for heat dissipation.

Application: The L7912CV is commonly used in various electronic devices and circuits where a stable negative voltage supply is required, such as in audio amplifiers, power supply circuits, and instrumentation.

Input Voltage: The input voltage range for the L7912CV typically extends from a few volts above the desired output voltage up to a maximum of around 35 volts.

Output Voltage Accuracy: The output voltage of the L7912CV is regulated to within a specified accuracy range, typically around ±4%.
