PMIC - Voltage Regulators - DC DC Switching Regulators.

The LM2574N-12G is a dual output monolithic step-down conversion regulator. Operating as a voltage regulator, it takes an input voltage of 12V, and outputs a lower, regulated voltage. The regulator can be set to any voltage lower than 12V, allowing for easy adjustability to get the desired output. The device is designed for switch mode power supply applications such as distributed power systems, and telecommunication systems. It is also suitable for use as a general purpose voltage regulator in other applications. The LM2574N-12G is an adjustable version of the LM2574-12, it offers voltage options from 1.23V up to 12V, with output currents of up to 1.5A. The device includes internal overvoltage, short-circuit, over-current and thermal shutdown protection to ensure that it operates safely within its rated parameters. The regulator features a wide input voltage range of 4.5V to 32V, making it suitable for use in a range of applications, including automotive and solar. It also operates with a wide operating temperature range of -40°C to 125°C, giving it good reliability and efficient operation. The regulator has a high power efficiency of up to 92%, and is designed to provide low ripple and noise levels. It features low quiescent current, current limited and low dropout voltage. The device can be enabled/disabled using an open drain control pin. The LM2574N-12G includes internal compensation to simplify design, and is available in a 5-pin TO-220 package. The device is heat sinkable, allowing for efficient operation in high-power applications. Overall, the LM2574N-12G is an ideal solution for applications that require adjustable output voltage and low ripple noise levels. Its wide range of features and wide operating temperature range make it a popular choice for various applications.
