LM2596S 3.3V Fixed Step Down Switching Regulator IC - TO-263-5 SMD Package

The LM2596S is a monolithic integrated circuit designed for step-down (buck) voltage regulation applications. This version provides a fixed 3.3V output and can deliver up to 3A of continuous load current. With internal thermal shutdown, current limit protection, and high efficiency, it is widely used in power supply circuits for microcontrollers, embedded systems, and communication devices. The compact TO-263-5 surface-mount package makes it suitable for space-constrained designs.Features of LM2596S – 3.3V Fixed Switching Regulator IC:Fixed 3.3V output for regulated power supplyUp to 3A continuous output currentHigh efficiency up to 75–90%Requires only a few external componentsBuilt-in thermal shutdown and current limit protectionSwitching frequency: 150 kHz (typical)Ideal for battery-powered and embedded systemsSpecifications of LM2596S – 3.3V Regulator IC:Model: LM2596S-3.3Output Voltage: 3.3V (fixed)Output Current: 3A (maximum)Input Voltage Range: 4.5V to 40VEfficiency: Up to 90%Switching Frequency: 150 kHzPackage: TO-263-5 – SMDOperating Temperature Range: -40°C to +125°CPackage Includes:1 × LM2596S – 3.3V Fixed Step Down Switching Regulator IC – TO-263-5 Package
