ON Semiconductor LM2576D2T-15 Voltage Regulator

The ON Semiconductor LM2576D2T-15 is a highly efficient, monolithic integrated circuit voltage regulator designed for a wide range of applications. This regulator provides all the active functions necessary for a step-down (buck) switching regulator capable of driving a 3A load with excellent line and load regulation. The LM2576D2T-15 is a fixed output voltage version that provides a 15V output.

This voltage regulator is simple to use and requires a minimum number of external components to operate. The device integrates a fixed-frequency oscillator, a temperature-compensated reference, a high-gain error amplifier, a current-limiting circuit, and a high-current output switch. The precision of the output voltage is maintained over a wide range of input voltages and output loads by the high-gain error amplifier and a tight tolerance reference voltage.

The LM2576D2T-15 is designed with thermal shutdown and current limit features to protect itself under overload conditions. Additionally, the device offers a low-power standby mode, which reduces power consumption when the regulator is not in use. The regulator's high efficiency is achieved through the use of ON Semiconductor's proprietary switch-mode design and is further enhanced by the use of an external Schottky diode for the catch diode application.

This product comes in a TO-263 package, which is suitable for surface-mount technology and provides a compact solution for space-constrained applications. It is commonly used in consumer electronics, office equipment, and industrial control systems, where a stable and efficient power supply is crucial.

The LM2576D2T-15 is characterized by its ease of use, robust protection features, and reliable performance, making it an ideal choice for designers looking for a simple and cost-effective voltage regulation solution.
