 7805 is a voltage regulator

 7805 is a voltage regulator integrated circuit (IC) that provides a constant output voltage of 5 volts, regardless of the input voltage supplied to it. It is a popular linear voltage regulator that is widely used in various electronic circuits to provide a stable power supply.

The 7805 IC is designed to regulate the voltage level of the input voltage between 7 volts and 35 volts, which makes it suitable for a wide range of applications. The IC contains three pins, where the input voltage is supplied through the input pin, and the output voltage is obtained from the output pin. The third pin is the ground or the common pin, which is used as a reference point for the input and output pins.

The 7805 IC is a type of positive voltage regulator, which means that the output voltage is always higher than the ground or common voltage. The IC is designed to provide a fixed output voltage of 5 volts, which is used to power various electronic components, such as microcontrollers, sensors, and other electronic circuits.

The 7805 IC is a simple and effective solution for voltage regulation, and it is widely used in various electronic circuits due to its low cost, simplicity, and reliability. However, it is important to note that the IC has a maximum current rating of 1 ampere, which means that it should not be used to power high-current devices. Additionally, the IC can generate heat during operation, and it is recommended to use a heat sink to dissipate the heat and prevent damage to the IC.

  SCR (Silicon Controlled Rectifier) An SCR (Silicon Controlled Rectifier) is a four-layer semiconductor device that acts as a switch, used for controlling high-power circuits in various electronic applications. The SCR can be turned on by applying a small voltage to its gate terminal, which allows a larger current to flow through the device. Once the SCR is turned on, it remains to conduct even after the gate voltage is removed, until the current flowing through it drops below a certain level. The basic structure of an SCR consists of four layers of alternating p-type and n-type semiconductor materials. The gate terminal is connected to the middle layer of the SCR, which acts as a control electrode. The anode (positive terminal) is connected to one end of the SCR, and the cathode (negative terminal) is connected to the other end. When a voltage is applied across the anode and cathode, no current flows through the SCR, as it is in a non-conducting or blocking state. However, when ...
