7805 Voltage Regulator IC

The 7805 voltage regulator IC is a three-terminal voltage regulator IC. A 7805 voltage regulator with a fixed output voltage is used in various applications. This is available through various packages like SOT-223, TO-263, TO-220, and TO-3. Among these, the TO-220 is the most used one. 

The IC 7805 is available in the TO220 package. It employs built-in current limiting, thermal shutdown, and safe operating area protection which makes them virtually immune to damage from output overloads.

7805 voltage regulator, although designed primarily as a fixed voltage regulator can also be used with external components for adjustable voltages and currents. With adequate heatsinking, they can deliver more than 0.5A output current.

Features:

  • Three-terminal positive voltage regulator IC

1. What is an IC 7805?

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.

2. What is the use of IC 7805?

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.

3. What is the input voltage range of IC 7805?

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.

4. How much current can LM7805 handle?

The LM7805 voltage regulator can handle a maximum output current of 1.5A when adequately heatsinked.

5. Which is better LM317 or LM7805?

The choice between the LM317 and LM7805 depends on specific requirements regarding output voltage and current capabilities.LM317:

FeatureLM317LM7805
Output Voltage RangeAdjustable from 1.25V to 37VFixed at 5V
Output Current CapacityUp to 1.5ATypically less than 1.5A
External ComponentsRequires additional components (e.g., potentiometer, precision resistors) for voltage adjustmentNo need for external components; connect input voltage source (minimum 7V)
