From Makers Electronics's description

LM2576T-5.0 Buck 5V 3A 40V DC-DC Converters DIP IC TO-220-5 The LM2576T-5.0 is a monolithic switching regulator IC designed for efficient DC-DC step-down (buck) voltage conversion. It provides a fixed 5V output with up to 3A load current, making it suitable for powering microcontrollers, embedded systems, and other digital circuits. The device integrates the main switching regulator functions in a single chip, simplifying power supply design and reducing the number of external components required. Operating with a wide input voltage range up to 40V, the LM2576 series offers improved efficiency compared to traditional linear regulators. It features internal frequency compensation, a fixed switching frequency oscillator, and built-in protection functions such as thermal shutdown and current limiting. Its TO-220-5 through-hole package allows easy mounting and good heat dissipation, making it widely used in industrial electronics, embedded systems, and power supply modules. Features: Fixed 5V output voltage. 3A output current capability. Wide input voltage range: 4V to 40V. High efficiency up to 77%. Requires only four external components. 52kHz fixed frequency operation. TTL shutdown capability. Low power standby mode. Thermal shutdown and current limit protection. Specification: Category Details Model Number LM2576T-5.0 Voltage Regulators – DC DC Switching Regulators Step-Down (Buck) Converter Part Status Active Function Step-Down Output Configuration Positive Topology Buck Output Type Fixed Number of Outputs 1 Voltage – Input (Min) 4V Voltage – Input (Max) 40V Voltage – Output (Min/Fixed) 5V Current – Output 3A Frequency – Switching 52kHz Synchronous Rectifier No Operating Temperature -40°C ~ 125°C (TJ) Mounting Type Through Hole Package / Case TO-220-5 Pinout: Pin Number Pin Name Description 1 VIN Supply input (40V max).
