LM2575T-Adj - Voltage Regulator

LM2575T-Adj: 1A Adjustable Step-Down Voltage Regulator IC

The LM2575T-Adj is a high-performance monolithic integrated circuit designed for efficient step-down (buck) voltage regulation. It provides all active functions required to deliver a stable 1A load current with excellent line and load regulation. This versatile device offers an adjustable output voltage, making it suitable for a wide range of applications. Engineered for simplicity, it requires only a minimum number of external components, streamlining your circuit design. Featuring internal frequency compensation and a fixed 52 kHz oscillator, it ensures reliable and consistent operation. The LM2575T-Adj serves as a high-efficiency alternative to traditional three-terminal linear regulators. Its superior efficiency significantly reduces the need for large heat sinks, often eliminating them entirely. Benefit from a wide input voltage range up to 57V, enhancing its adaptability in diverse power supply designs. This regulator is an ideal choice for compact, power-efficient solutions where space and thermal management are critical.
