Voltage Regulator 78xx
The 78xx series is a common family of voltage regulators. Here are some key points about them: The 78xx series provides a fixed positive output voltage, where "xx" is replaced by the specific voltage value (e.g., 7805 for 5 volts, 7812 for 12 volts, etc.). They are relatively simple to use and offer stable voltage regulation. They typically have three terminals: input, output, and ground. The input voltage should be higher than the desired regulated output voltage. These regulators have good load regulation and can supply a moderate amount of current to the load. They are often used in various electronic circuits to provide a constant voltage source for components that require a specific voltage level. However, they do have some limitations, such as a relatively low efficiency and the need for a suitable heat sink to dissipate heat when operating at higher currents. Some advantages of the 78xx voltage regulators include their simplicity, wide availability, and ease of implementation in circuits. They are commonly found in power supplies for small electronic devices, instrumentation, and other applications where a stable fixed voltage is needed.
