LM2576T5.0 (NOPB) — TO2205, singlepiece efficiency, fixed 5.0V stepdown (buck) regulator in a TO2205 package. Lead (NOPB) plating. Why this part helps Efficiently converts higher DC voltages down to a stable 5.0V rail with much lower heat dissipation than linear regulators, enabling compact, reliable power designs. Integrates switching control, power switch, current limiting and thermal shutdown into one device, simplifying design and improving protection. Requires only a few external components (inductor, Schottky diode and input/output capacitors), reducing board space and assembly time. Key benefits at a glance Delivers up to 3A continuous output current for powering microcontrollers, sensors, small singleboard computers and other 5V loads. Fixed 5.0V output simplifies design when a regulated 5V rail is required. Widely compatible input range (suitable for common DC sources such as 12V and 24V supplies and many battery configurations). Lead (NOPB) TO2205 package for easy throughhole mounting and reliable thermal contact to heatsinks. Key attributes Model: LM2576T5.0 (NOPB) Package: TO2205 (throughhole) Output: Fixed 5.0V Output current capability: up to 3A Switching regulator topology: stepdown (buck) Protection: builtin current limit and thermal shutdown External components required: inductor, catch diode (Schottky recommended), input and output capacitors Compliance: NOPB (lead plating) Performance and design considerations Designed for efficiency switching regulation, minimizing power loss compared with linear regulators at moderate to inputtooutput differentials. Typical switching frequency in the LM2576 family provides a good balance between component size and performance; external inductor and capacitor selection will determine transient response and ripple. Thermal management: the TO2205 package can be mounted to a heatsink for sustained current operation; the device includes thermal shutdown for protection under overload or elevated temperature. Simple application circuit: minimal external passive components make it straightforward to implement a reliable 5V supply. Typical applications / use cases Automotive and vehicle electronics: step down 12V vehicle battery voltage to a regulated 5V rail for microcontrollers, sensors and infotainment peripherals (use appropriate input transient protection if required). Embedded and industrial control: lowcost, compact 5V power supply for PLCs, data acquisition modules, motor controllers and sensors where an efficient 3Acapable regulator is required. Batterypowered and portable equipment: convert multicell battery packs or higher DC rails down to 5V to power embedded controllers, display modules and communications interfaces while preserving battery life. What you get One LM2576T5.0 (NOPB) in a TO2205 package, ready for integration into throughhole or heatsinkmounted power designs. Simple to implement and widely used in industrial, automotive and embedded power conversion applications.
