The LM2596 regulator is a monolithic integrated circuit ideally suited for the easy and convenient design of a step−down switching regulator (buck converter). It is capable of driving a 3.0A load with excellent line and load regulation. This regulator module is suitable for voltage converting circuits in your project. The blue terminal block on the module is to input power when the two rows of pins are to output power – one for positive (marked with "+") and the other for GND.
