The MC7805CTG from ON Semiconductor is an Linear Voltage Regulator IC featuring a fixed positive output voltage of 5V, a 1A output current, and a TO-220 package type. It is a three terminal integrated circuit designed to provide a precise 5V output voltage from a variable input voltage in the range of 6.5V to 16V. The output voltage is maintained with high accuracy and low temperature coefficient even when the input voltage changes substantially. This IC also has several protection features including current limit, thermal overload, and reverse polarity protection. It is widely used in consumer electronics, automotive applications, and industrial applications.
