LM7805 Positive Voltage Regulator TO-220 5V

Description

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 except noise voltage and ripple rejection ratio are measured using pulse techniques (t w ≤ 10 ms, duty cycle ≤ 5%). Output voltage changes due to changes in internal temperature must be taken into account separately.
