Key Features
- Wide Input Range (4.5V-40V): Accept power from batteries, solar panels, laptop adapters, or automotive 12V/24V systems with ease.
- Adjustable Output (1.25V-37V): Dial in your exact target voltage using the onboard multi-turn potentiometer - from 1.25V for low-power logic up to 37V for motor drivers.
- High Efficiency (Up to 92%): Switching regulator topology generates significantly less heat than linear regulators, reducing wasted energy and eliminating the need for bulky heatsinks in most applications.
- 3A Continuous Output: Comfortably powers Arduino, Raspberry Pi, ESP32, servo motors, relay modules, LED strips, and other moderate-load devices.
- Built-In Protection: Overcurrent limiting, thermal shutdown, and short-circuit protection safeguard both the module and your connected circuit.
- Ultra-Compact Form Factor: Tiny PCB footprint (43mm x 21mm) fits into enclosures, breadboard setups, and tight project spaces without difficulty.
- Low Output Ripple: Clean regulated output (<=30mV ripple) suitable for powering noise-sensitive analog circuits and microcontrollers.
- Drop-In Replacement: Direct substitute for inefficient 7805/78xx linear regulators in existing designs - simply swap and adjust.

How It Works
The LM2596 is a monolithic integrated circuit that functions as a step-down (buck) switching voltage regulator. It rapidly switches the input voltage on and off at 150 kHz, and the onboard inductor and capacitor smooth this pulsed energy into a stable DC output. By turning the potentiometer, you adjust the feedback voltage divider ratio, which changes the regulated output voltage. This switching approach is far more efficient than linear regulation - instead of burning excess voltage as heat, the buck converter only draws the energy actually needed by your load.
How to Use
- Connect Input Power: Wire your DC source (4.5V-40V) to the IN+ and IN- pads on the module. Observe correct polarity - reverse polarity can damage the module.
- Adjust Output Voltage BEFORE Connecting Load: With input power applied and NO load connected, use a multimeter on the OUT+ and OUT- pads. Turn the potentiometer (small brass screw) clockwise or counterclockwise until the multimeter reads your desired output voltage.
- Connect Your Load: Once the output voltage is confirmed, wire your target device or circuit to the OUT+ and OUT- pads.
