The LM2575T-3.3G from ON Semiconductor is a monolithic integrated circuit designed for easy and convenient design of step-down switching regulators (buck converters). This device is capable of driving a 1.0 A load with excellent line and load regulation, featuring a fixed 3.3V output voltage.
Key electrical specifications include a wide input voltage range of 4.75V to 40V and a fixed switching frequency of 52kHz. The regulator offers high efficiency, significantly higher than linear regulators, which can reduce or eliminate the need for a heatsink. It operates within a temperature range of -40°C to 125°C (TJ).
Packaged in a standard TO-220-5 configuration, this component is suitable for through-hole mounting. The design minimizes external components, simplifying power supply design. It includes thermal shutdown and current limit protection for enhanced reliability.
This switching regulator is well-suited for applications requiring efficient voltage conversion in a compact form factor. Its fixed output voltage and current handling capabilities make it a versatile choice for various power supply designs.
