LM2596-ADJ (IL2596-ADJ) 3A Voltage Regulator IC TO-220-5L Package

LM2596-ADJ (IL2596-ADJ) 3A Voltage Regulator IC TO-220-5L Package 

The LM2596-ADJ (also known as IL2596-ADJ) is a high-efficiency step-down (buck) switching voltage regulator with an adjustable output voltage, capable of delivering up to 3A output current. Its switching regulation design provides high efficiency, significantly reducing heat generation compared to linear regulators, making it suitable for high-current, compact power supply designs.

This IC integrates the switching transistor, oscillator, control circuitry, and protection features into a single device, requiring only a few external components to implement a complete adjustable DC-DC converter. The TO-220-5L through-hole package ensures good thermal performance and easy mounting on a heatsink for high-power applications.
