LM2596S-ADJ Low-Ripple High Efficiency Module

The LM2596S-ADJ Low-Ripple High Efficiency module is an adjustable step-down (buck) converter built around the LM2596S-ADJ regulator. It converts a higher DC voltage, such as 12 V or 24 V, to a lower voltage that you set with the on-board trimmer, with much less heat than a linear regulator. This version is sold as a low-ripple board for microcontrollers, sensors and other circuits that need a clean, stable supply.

LM2596S-ADJ Low-Ripple Module Specifications

• Regulator chip: LM2596S-ADJ adjustable buck regulator
• Input voltage: up to 40 V DC
• Output voltage: adjustable from about 1.25 V, staying at least about 1.5 V below the input
• Output current: 3 A rated; about 2 A continuous is recommended without extra cooling
• Switching frequency: 150 kHz
• Adjustment: trimmer potentiometer on the board

LM2596S-ADJ Low-Ripple Module Applications

• Powering Arduino, ESP32 and Raspberry Pi projects from 12 V or 24 V supplies
• Clean supply rails for sensors and audio circuits
• Running 5 V or 3.3 V modules from a car battery or solar panel
• Adjustable bench supply for testing circuits

What's in the Box

• 1 × LM2596S-ADJ low-ripple step-down module

Tip: Set the output voltage with a multimeter before you connect your load: power the input, measure across the output and turn the trimmer screw slowly. Double-check the input polarity, because reversing it can destroy the regulator.
