7806 Voltage Regulator IC
7806 Voltage Regulator IC
The 7806 is a three-terminal positive voltage regulator IC (Integrated Circuit) designed to provide a stable and regulated output voltage of 6V. It is a popular and widely used voltage regulator in electronic circuits, ideal for applications where a fixed and stable output voltage is required.
The 7806 voltage regulator IC is designed to convert an unregulated input voltage to a regulated output voltage of 6V. The IC takes an input voltage from a power source, such as a battery or a transformer, and converts it into a stable output voltage that can be used to power electronic circuits. The regulator operates by comparing the output voltage to a reference voltage and adjusting the current flow to maintain a constant output voltage.
