LM7805 Voltage Regulator
LM7805 Voltage Regulator: The LM7805 is a popular voltage regulator IC that provides a constant output voltage of 5V. It is a three-terminal regulator, meaning it has an input terminal, an output terminal, and a ground terminal. It is commonly used to provide a stable 5V power supply for electronic circuits, such as microcontrollers, sensors, and other devices that require a regulated voltage source.
The LM7805 has several features that make it useful in a wide range of applications. Some of these features include:
- Low dropout voltage: The LM7805 can still provide a stable 5V output voltage even when the input voltage is only slightly higher than the output voltage.
- High output current capability: The LM7805 can provide up to 1A of output current, making it suitable for powering a wide range of devices.
- Thermal protection: The LM7805 has thermal protection that prevents it from overheating and damaging the circuit.
- Short-circuit protection: The LM7805 also has built-in protection against short-circuits, which can help prevent damage to the circuit.
Specification:
- Supply Voltage: 35 V (max)
- Output Voltage: 5 V
- Output Current up to 1A
- Operating Temperature: 0 to 125 degree Centigrade
