🔧 DIY Voltage Regulator Circuit | 12V to 5V Using Zener Diode & Resistor

In this video, learn how to build a super simple voltage regulator circuit that converts 12V DC to stable 5V DC using just a Zener diode and resistor – no voltage regulator IC required!

This is a great solution for low-current applications, powering 5V sensors, or protecting sensitive components in electronics DIY.

✅ What You’ll Learn:
✔ How a 5V Zener diode regulates voltage
✔ Role of current-limiting resistor (100Ω)
✔ When and where to use this simple circuit
✔ Safe voltage dropping for low-power electronics

🔧 Components Used:

1x Zener Diode (5V)

1x 100 Ohm Resistor

12V DC Input (Battery or Adapter)

5V DC Output

⚠️ Note: This circuit is ideal for low-power devices only. For devices that need higher current, consider using a 7805 voltage regulator IC or buck converter.
