LM2596-12 (IL2596-12) 3A 12V Fixed Voltage Regulator SMD IC (TO-263-5L Package)

LM2596-12 (IL2596-12) 3A 12V Fixed Voltage Regulator SMD IC (TO-263-5L Package) 

The LM2596-12 (also known as IL2596-12) is a high-efficiency step-down (buck) switching voltage regulator designed to provide a fixed 12V output with up to 3A output current. It operates at high switching efficiency, significantly reducing heat dissipation compared to linear regulators, making it ideal for power supply and DC-DC conversion applications.

This IC integrates the switching transistor, oscillator, control, and protection circuitry into a single package, requiring only a few external components to build a complete and efficient power supply. Housed in a TO-263-5L (D²PAK) surface-mount package, it offers good thermal performance and is suitable for compact, high-power designs.
