Pinout
The L7805CD2T is a voltage regulator from the L78xx series, designed to provide a fixed 5V output. It typically comes in a DPAK package, which has 3 pins. The pin functions are as follows:
1. Input (IN): This pin receives the unregulated input voltage, which should be higher than the desired output voltage (typically 7V to 20V for proper operation).
2. Ground (GND): This pin is connected to the ground of both input and output voltage circuits. It serves as a common reference point.
3. Output (OUT): This pin provides the regulated output voltage of 5V. It connects to the load that requires the stable voltage source.
This voltage regulator is used in applications needing a constant 5V supply, offering features like internal current limiting, thermal shutdown, and safe area protection. The DPAK package is suitable for surface mounting, making it useful in compact electronic designs.
