The LM2575T-12 is a high-performance step-down voltage regulator IC component manufactured by Texas Instruments. It is part of the LM2575 series of regulators that are designed to deliver efficient and reliable power supply solutions for various applications. This specific variant, the LM2575T-12, is configured to provide a fixed output voltage of 12 volts.
One of the key features of the LM2575T-12 is its ability to operate over a wide input voltage range, from 4.5 volts to 40 volts. This makes it suitable for various input sources, including automotive batteries, industrial power supplies, and battery adapters. It can efficiently regulate the input voltage and provide a stable 12-volt output even when the input voltage fluctuates or is higher than the desired output.
The IC utilizes a PWM (Pulse Width Modulation) control technique for regulation, ensuring high efficiency and low power dissipation. It is capable of delivering up to 1A (amperes) of output current, making it suitable for powering a wide range of loads such as microcontrollers, sensors, motor drivers, and other electronics.
The LM2575T-12 incorporates internal circuitry for thermal shutdown, current limiting, and overvoltage protection, enhancing its reliability and safeguarding against damaging conditions. It also features a built-in soft-start function that minimizes inrush current during startup, preventing excessive stress on the components and improving system longevity
