L7812CV Linear Voltage Regulator, 7812, Fixed, Positive, 19V To 35V In, 12V And 1.5A Out, TO-220-3

Description

• Voltage Regulation: The “78” series voltage regulators, including the L7812CV, are known for their ability to regulate the output voltage to a fixed value. In this case, it provides a regulated 12 volts output.
• Package Type: The “TO-220” package is a standard through-hole package commonly used for voltage regulators. It has a metal tab that can be used for heat dissipation when mounted on a suitable heatsink.
• Input Voltage Range: The L7812CV typically requires an input voltage higher than the desired output voltage. It can handle input voltages from 19V to 35V, making it suitable for a wide range of applications.
• Output Current: The maximum output current the L7812CV can supply is determined by the package and its ability to dissipate heat. Commonly, it can handle currents up to 1.5 amperes (1.5A), but the exact value may vary depending on the manufacturer and package. The regulator can provide a stable 12V output within its specified current range.
• Regulation: It offers a fixed voltage output, which means it maintains the output voltage close to 12V even when there are variations in the input voltage and load conditions.
• Applications: Voltage regulators like the L7812CV are used in a wide range of applications, including powering digital and analog circuits, microcontrollers, sensors, and other electronic components.
• Heat Dissipation: For high-current applications or when the input voltage is significantly higher than the output voltage, a heatsink may be required to dissipate heat and prevent overheating of the regulator.
• Output Protection: It may have protection features such as over-temperature shutdown and over-current protection.
• Pin Configuration: The component typically has three pins: input (Vin), ground (GND), and output (Vout).
• Use of Decoupling Capacitors: It’s common practice to include decoupling capacitors (typically in the range of 100nF to 10µF) at the input and output to stabilize the regulator and reduce noise.
