The 7805 series of three terminal positive regulators are available in the TO-220 package and with several fixed output voltages, making them useful in a wide range of applications. Each type employs internal current limiting, thermal shut down and safe operating area protection, making it essentially indestructible. If adequate heat sinking is provided, they can deliver over 1A output current. Although designed primarily as fixed voltage regulators, these devices can be used with external components to obtain adjustable voltages and currents.

Description
The 7805 operates by maintaining a constant voltage drop across it, regardless of changes in the input voltage or load current. It is capable of regulating the output voltage even when there are fluctuations or variations in the input voltage.
The maximum input voltage that the 7805 can handle depends on the specific variant, but it is typically around 35 volts. It can provide a maximum output current of 1A (amperes), although there are higher-current variants available.
The 7805 is widely used in various electronic circuits to provide a stable and regulated +5V power supply. It is commonly employed to power microcontrollers, digital logic circuits, sensors, and other components that require a reliable voltage source.
It is important to note that the 7805, like other linear regulators, dissipates excess voltage as heat. Therefore, if the input voltage is significantly higher than the desired +5V output voltage, or if the load current is high, a heatsink may be required to prevent the regulator from overheating. Additionally, proper decoupling capacitors should be used at the input and output pins to stabilize the voltage and suppress noise.
