LM7805 Voltage Regulator IC - 5 Volt

Fixed 5-Volt Output: The LM7805 is a fixed-output voltage regulator, meaning it provides a constant 5-volt output voltage regardless of changes in the input voltage or load conditions.

Input Voltage Range: The LM7805 is typically used to regulate input voltages between 7 volts and 35 volts, although it can handle higher input voltages for short durations with proper heat sinking.

Linear Regulator: The LM7805 is a linear voltage regulator, which means it dissipates excess energy as heat. This heat dissipation is an important consideration when using the IC, and it may require a heat sink for higher power applications.

Current Rating: The LM7805 is available in different versions with varying current ratings, typically 0.1A (100mA), 0.5A (500mA), and 1.0A (1,000mA) being common. You should choose the appropriate version based on your current requirements.

Internal Thermal Overload Protection: The LM7805 includes thermal overload protection that limits the output current when the IC's temperature exceeds a certain threshold. This protection helps prevent damage to the IC.

Pin Configuration: The LM7805 has three pins—input (Vin), ground (GND), and output (Vout). Proper input and output capacitors are often used to improve stability.

Applications: The LM7805 is used in a wide range of applications, including powering microcontrollers, logic ICs, sensors, and other electronic components from higher voltage sources. It is also commonly used in power supply designs.
