The LM7805 7805 IC is a three-terminal positive linear voltage regulator designed to provide a stable 5V DC output from a suitable higher DC input. Its fixed-output design makes it a practical choice for Arduino projects, sensor circuits, IoT devices, microcontroller boards, DIY power supplies, and other electronics applications that require a regulated 5V rail.
This 5V voltage regulator IC is available in a commonly used TO-220 package, making it easy to mount on breadboards, PCBs, and prototype circuits. The regulator includes internal current limiting, thermal shutdown, and safe-area protection to help protect the device during overload conditions.
The 7805 is particularly useful when a simple fixed 5V supply is required without using a more complex switching regulator circuit. For higher current loads, adequate heatsinking may be required because a linear regulator dissipates excess input voltage as heat. Always check the input-voltage and thermal limits of the exact device before use.
Know why the 7805 Voltage Regulator is essential in electronics.
Also, check the 7812 Voltage Regulator IC with an operating output voltage of 12V.
| Input voltage | 7v to 25v |
| Output voltage range | 4.8 v to 5.2v |
| Typical output voltage | 5v |
| Maximum output current | 1.5A |
| Dimensions | 30 x 10 x 5 mm |
| Weight | 2g |
7805 is a three-terminal linear voltage regulator IC with a fixed output voltage of 5V which is useful in a wide range of applications. The 7508 IC price ranges from 5 INR to 15 INR in India.
Applications for the 7805 IC voltage regulators are current regulators, dual regulated power supplies, phone charger build-up circuits, UPS power supply circuits, etc. 7805 IC use can also be seen in fixed output regulators and adjustable output regulators, etc.
The function of pin 1 is to supply the input voltage. Must be in the range of 7V to 35V. Apply an unregulated voltage to this pin for regulation. At 7.2V input, the PIN reaches maximum efficiency.
The LM7805 voltage regulator can handle a maximum output current of 1.5A when adequately heatsinked.
The choice between the LM317 and LM7805 depends on specific requirements regarding output voltage and current capabilities.LM317:
| Feature | LM317 | LM7805 |
|---|---|---|
| Output Voltage Range | Adjustable from 1.25V to 37V | Fixed at 5V |
| Output Current Capacity | Up to 1.5A | Typically less than 1.5A |
| External Components | Requires additional components (e.g., potentiometer, precision resistors) for voltage adjustment | No need for external components; connect input voltage source (minimum 7V) |
Yes, a 7805 can be used to create a regulated 5V supply for suitable Arduino and electronics circuits, provided the input voltage, output current and thermal dissipation are within the regulator's limits. Check the power requirements of the specific Arduino board and connected components before connecting the supply.
I am getting 4v instead of 5v constant out voltage
