LM7805 Positive Voltage Regulator TO-220 5V

The LM7805 Positive Voltage Regulator TO-220 5V is a three-terminal linear regulator that provides a fixed 5V DC output from a higher voltage input. It is widely used in electronic circuits to ensure a stable and regulated power supply, protecting sensitive components from voltage fluctuations. The LM7805 regulator incorporates internal current limiting, thermal shutdown, and safe operating area protection, making it a robust choice for various applications.

Features
  • Provides a fixed 5V output voltage.
  • Output current up to 1.5A with proper heat sinking.
  • Internal thermal overload and short-circuit protection.
  • Requires minimal external components for operation.
  • Available in standard TO-220 package for easy mounting.

All characteristics are measured with a 0.22-μF capacitor from input to ground and a 0.1-μF capacitor from output to ground. All characteristics except noise voltage and ripple rejection ratio are measured using pulse techniques (tw ≤ 10 ms, duty cycle ≤ 5%). Output voltage changes due to changes in internal temperature must be taken into account separately.

Note: Complete Technical Details can be found on the LM7805 datasheet given at the end of this page.
