Microchip Technology's LM2576-3-3BT is a monolithic integrated circuit providing all the functions of a step-down (buck) switching regulator with ±3% tolerance on the output voltage. This device is capable of driving a 3A load with excellent line and load regulation. The LM2576-3-3BT features a fixed 3.3V output voltage and operates at a switching frequency of 52kHz. Its internal oscillator and fixed frequency provide a predictable switching pattern, simplifying filter design. The device is available in a TO-220-5 package suitable for through-hole mounting. It requires minimal external components and is designed for a wide input voltage range of 4V to 40V. Key applications include voltage regulation in industrial control systems, power supplies for communication equipment, and various consumer electronics. The operating temperature range is -40°C to 125°C.
