L7805CV Schematic Diagram

The internal circuit of L7805 three-terminal voltage regulator IC has the functions of overvoltage protection, overcurrent protection and overheat protection, which makes its performance very stable. Therefore, it can achieve more than 1A output current. The device also has a good temperature coefficient, so the product has a wide range of applications. Local regulation can be used to eliminate the influence of noise and solve the dispersion problem related to single-point regulation. The output voltage error accuracy is ±3% and ±5%.
