The LM2575T-5.0/NOPB is a switching voltage regulator from Texas Instruments. It is a 1A step-down voltage regulator with an adjustable output voltage range of 1.23V to 16V. It is capable of providing up to 1A of output current and is designed to operate over a wide temperature range from -40°C to 125°C. The LM2575T-5.0/NOPB offers fast transient response, low ripple, and excellent line and load regulation. It also features low external component count, high efficiency, thermal-shutdown protection, and current-limit protection. This voltage regulator is ideal for high-density, low-power applications such as cell phones, laptops, and PDAs.
