High Current Adjustable Power Supply | LM317 + 2SC5200 #electronic #diy #voltageregulator

Подробнее о видео

This video shows how to build a high current adjustable DC power supply using an LM317 voltage regulator combined with a 2SC5200 power transistor. The LM317 sets the output voltage, while the 2SC5200 handles higher current loads that the LM317 alone cannot manage.

🔧 Main Features:

Adjustable Output Voltage using 10K Potentiometer

High Current Output thanks to 2SC5200

Smooth and precise regulation

Ideal for lab bench supplies, testing, and powering DC devices

🧩 Key Components:

LM317 Adjustable Regulator

2SC5200 Power Transistor

10K Potentiometer

Resistors: 120Ω, 240Ω, 1kΩ, 100Ω

Input Voltage: 12V–36V DC

Output Voltage: Adjustable (~1.25V to near input level)

💡 How It Works:
The LM317 controls the base of the 2SC5200 via a resistor network and potentiometer. When the load requires more current than the LM317 can provide, the 2SC5200 bypasses current directly from input to output while maintaining the regulated voltage.

⚠️ Tip: Add a heatsink to both LM317 and 2SC5200 for stable performance.
