The L78L12CD13TR is a member of the Voltage Regulator Linear family of power management integrated circuit (PMIC) products from STMicroelectronics. It is a three-terminal regulator with adjustable output voltage and a 12V nominal input voltage. The device is designed to provide a regulated output voltage of up to 11V due to its high efficiency. The device also has an extended temperature range operation, with a junction temperature range of -40°C to +85°C. The L78L12CD13TR is used in applications such as automotive, computing, consumer electronics, industrial, lighting, and healthcare.The new L78L12CD13TR includes several improved features compared to its predecessors. It provides a better output accuracy, a lower quiescent current, and a smaller package size. It also includes circuitry to ensure the highest reliability over temperature. On the other hand, this device has a higher output voltage drop than its competitors at high loads, but its accuracy is still high enough for most applications.The L78L12CD13TR is designed to simplify power supplies for professional applications. It does not require external components and provides excellent temperature compensation and stability, making the design job simpler and faster. The device is readily available in industry-standard TO-220 packages.The L78L12CD13TR has a very simple and straightforward working principle. It is a linear regulator, meaning that it works by taking in a voltage input and outputting a regulated and exact voltage. This is accomplished by allowing just enough current through the regulator to equal the voltage that is supplied over the input. The regulator uses an internal temperature compensation circuit to ensure that the output voltage will stay consistent regardless of temperature.The voltage regulator will maintain the output voltage until the current drawn through it reaches the current limit. At that point, the regulator will reduce the output voltage and control the current. This feature is important in the protection of the load and the internal circuitry.In summary, the L78L12CD13TR is a voltage regulator linear PMIC which is used in various applications such as automotive, computing, consumer electronics, industrial, lighting, and healthcare. The device has a very simple and straightforward working principle and several enhanced features such as improved output accuracy, a lower quiescent current, and a smaller package size for easier installation. It also provides excellent temperature compensation and stability. Therefore, the L78L12CD13TR is an efficient and reliable power solution.
