The LM2575D2T-ADJR4G from ON Semiconductor is a monolithic integrated circuit designed for easy and convenient design of step-down (buck) switching regulators. This device is capable of driving a 1.0 A load with excellent line and load regulation.
Key electrical specifications include a wide input voltage range of 4.75 V to 40 V and an adjustable output voltage range from 1.23 V to 37 V, with a guaranteed ±4% tolerance. It operates at a fixed switching frequency of 52 kHz and requires only a few external components for operation. The regulator includes internal cycle-by-cycle current limiting and thermal shutdown for protection under fault conditions.
This component is supplied in a surface-mount D2PAK-5 package, suitable for automated assembly processes. The operating temperature range is -40°C to 125°C (TJ). Its high efficiency makes it suitable for applications where power dissipation needs to be minimized, often eliminating the need for a heatsink.
Applications include simple and high-efficiency step-down regulators. The adjustable output version offers design flexibility for various power supply requirements.
