Скачать или смотреть 7805 Regulator Circuit | Step-Down to 5V ⚡

In this video, learn how to build a simple voltage regulator circuit using the LM7805 IC to step down voltage to a stable +5V output. This regulator is perfect for powering Arduino, sensors, and other 5V logic devices from a higher voltage input.

🔧 Components Used:

LM7805 Voltage Regulator

10K Potentiometer (for voltage trimming or testing)

Power Supply (input: 7V–35V)


The LM7805 has 3 pins:
1️⃣ Input Voltage (+)
2️⃣ Ground (GND)
3️⃣ Regulated Output (5V)

💡 A must-know circuit for electronics beginners and makers!
