Design a Custom BoardThis SMD package requires a breakout board to interface with breadboards and standard prototyping layouts. The three-pin configuration with large copper pad underneath demands reflow soldering or careful hand-soldering to avoid cold joints, making a breakout board with standard 0.1" headers essential for reliable connections. Ideal for power regulators and MOSFETs where thermal performance and ease of iteration matter.
Adjustable step-down (buck) switching regulator capable of delivering 3A output current. Features internal 52kHz oscillator, thermal shutdown protection, and adjustable output voltage via external resistor divider. Commonly used in power supply designs requiring regulated lower voltages from higher input sources with moderate current demands.
