National Semiconductor LM2576T-5.0 Switching Regulator 3A TO220

A 3A step-Down voltage regulator that provides all the active functions for a step-down (buck) switching regulator. This device offers a high efficiency replacement for three-terminal type linear regulators, substantially reducing the degree of thermal management required. This regulator is a simple to use device, requiring only a minimum of external components, thus reducing component and assembly costs. Suitable applications for this device include: simple high efficiency buck regulation, pre-regulation for linear regulators, on-card switching regulators, positive to negative conversion (buck-boost).
