LM2596-3.3 (IL2596-3.3) 3A 3.3V Fixed Voltage Regulator IC TO-220-5L Package

The LM2596-3.3 (also known as IL2596-3.3) is a high-efficiency step-down (buck) switching voltage regulator that provides a fixed 3.3V output with up to 3A output current. Its switching regulation design ensures high efficiency, reducing power loss and heat generation compared to linear regulators, making it ideal for compact, high-current applications.

The IC integrates the switching transistor, oscillator, control circuitry, and protection features into a single device, requiring only minimal external components to build a complete DC-DC converter. Housed in a TO-220-5L through-hole package, it offers excellent thermal performance and easy mounting for high-current designs.
