🔹 Pro Tip

💡 At loads above 50 W, attach a heatsink or small fan to the regulator IC for extended life. The input voltage must exceed the output voltage by at least 1.5 V for stable regulation. Ideal as a variable bench supply for 3.3 V, 5 V, and 12 V testing.

⚠️ Note: Always ensure proper heat dissipation and correct voltage configuration before powering connected devices.
