The voltage regulator integrated circuit (IC) 7805 truly belongs to the 78xx series of voltage regulator ICs. A fixed linear voltage regulator, that is. The value of the fixed output voltage that this specific IC produces is represented by the xx included in the string “78xx.” It is a 5V DC controlled power supply for the 7805 IC. A provision for a heat sink is also included by this regulator IC. This voltage regulator’s threshold limit is 35V, and any input voltage less than or equal to that will result in a constant output of 5V from the IC.
7805 VOLTAGE REGULATOR Features:
Pin One Input
This pin’s job is to provide the input voltage. It should fall between 7 and 35 volts. To regulate it, we provide an unregulated voltage to this pin. The PIN operates at maximum efficiency with 7.2V input.
To this pin, the earth is connected. This pin is neutral for both input and output (0V).
OUTPUT PIN 3
The regulated output is received on this pin. There will be 5V.
