LM7805 Voltage Regulator – 5V Linear Regulator IC (TO-220) for Power Supply Circuits
The LM7805 is a popular linear voltage regulator IC that outputs a stable 5V DC from a higher input voltage. It is commonly used in power supplies, Arduino projects, sensor circuits, and other embedded systems where a consistent 5V power source is required. The TO-220 package makes it easy to mount and heatsink when needed.
 
Key Features:
Fixed 5V Output
Regulates higher input voltages down to a stable 5V DC output.
Wide Input Voltage Range
Accepts input from 7V to 35V for flexible power supply options.
High Current Capability
Delivers up to 1A output current (with proper heat dissipation).
Built-in Protection
Includes short circuit, thermal shutdown, and overvoltage protection.
TO-220 Package
Easy to mount on PCBs or heatsinks for temperature control.
 
Applications:
Power supply for Arduino, ESP32, and microcontrollers
Regulated 5V supply for sensors, displays, and modules
DIY electronics and robotics projects
Embedded systems and development boards
