Overview

This pack includes 5 pieces of L7805CV / 7805 positive linear voltage regulators in a TO‑220 package, each providing a fixed 5V output up to 1.5A. The regulators are widely used to power Arduino boards, sensors and other 5V logic circuits from higher DC input voltages.

Key features

• Fixed +5V output, up to 1.5A continuous load current (peak around 2.2A with proper heatsinking).
• Wide input voltage range, typically 7–25V DC for stable regulation.
• TO‑220 through‑hole package with 2.54mm lead spacing, easy for breadboard or PCB prototyping.
• Built‑in thermal shutdown and short‑circuit current limiting for safer projects.
• Commonly used in DIY 5V power supplies, Arduino projects, servo and sensor power rails.

Pin configuration (front view, pins downward)

1. Input: Connect 7–25V DC.
2. Ground: Common ground with your circuit.
3. Output: Regulated +5V DC.

Typical applications

• 5V power supply module for Arduino Uno, Nano and other 5V microcontroller boards.
• Regulated 5V rail for sensors, small DC motors or servos (with appropriate decoupling capacitors and heatsink).
• General 5V bench supply or adapter converter from 9V/12V DC sources for breadboard experiments.
