The L7806CD2T is a Positive Fixed Voltage Regulator with a maximum output current of 1.5A and is designed to provide voltage regulation with minimum space. It is designed to provide a regulated output from an input of 3V to 40V. The device operates from a single supply and provides a regulated 5V output. It incorporates current limiting and thermal shut-down circuits for protection from over-current and/or over-temperature conditions.

The L7806CD2T is a three terminal linear voltage regulator device that provides a regulated 5V output from an input of 3V to 40V. The device features an optimized design to achieve higher efficiency and lower heat dissipation. It is stable with a load capacitance of up to 47uF, making it suitable for high ripple load applications. The device also features a low voltage dropout voltage, typically 0.44V (at 1.5A load current) and a low quiescent current of only 8mA. It is available in a TO-252 (D-Pak) package.

The working principle of the L7806CD2T is approximately the same as the working principle of all linear voltage regulators, which is to regulate the output voltage at the desired level, regardless of the input voltage. Linear regulators utilize a three-terminal configuration, with an input voltage and an output voltage, with the third terminal connecting a reference voltage. This reference voltage, typically from a zener diode, is compared to a control voltage that is usually derived from a fraction of the output voltage (feedback voltage). The difference between the two voltages, which is called the error voltage, is used to control a pass element, usually a sequence of NPN or PNP transistors. The pass element is used to control the current passing through the device, allowing it to adjust the output voltage to the desired level.

The L7806CD2T is a great option for applications that require a compact, efficient and low cost voltage regulator. It is suitable for portable electronic devices, power supplies, battery operated products, telecom equipment, and industrial controls. Its low quiescent current, relatively low drop-out voltage, over current limitation and thermal shutdown make it a good choice for a variety of different applications.

In conclusion, the L7806CD2T is an excellent choice for users looking for a linear voltage regulator with a low drop-out voltage, high current output and integrated protection functions. The device is both cost-effective and space-saving and suitable for a wide variety of applications. With its high efficiency and low heat dissipation, it is quickly becoming the regulator of choice for many designers.
