efficient 3.3V step-down converter

The LM2596 3.3V TO263 SMD is an efficient step-down voltage regulator that converts input voltages from 4V to 40V into a stable 3.3V output, with up to 2A of continuous current. Designed in a compact TO263 SMD package, it’s perfect for powering microcontrollers, sensors, and other low-voltage devices in space-constrained applications.
