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) |
