What Stands Out
Compact Design
Measuring only 1.00 x 1.00 inches, this regulator fits easily into tight spaces, making it ideal for small projects requiring a reliable 3.3V power supply without compromising board size.
Efficient Performance
Featuring a step-down DC-DC conversion with a 2A output, this regulator ensures high efficiency and stable power delivery, making it perfect for projects that demand consistent voltage and current.
Heat Regulation
Equipped with a 0.6in x 0.5in copper pad, this breakout board effectively dissipates heat, enhancing performance and reliability during operation, ensuring long-term stability for your electronics.
