The LD2981ABM38TR is a polyphase synchronous buck regulator that is an example of a low drop-out linear voltage regulator. It is able to self-regulate voltage and can keep output voltage at a constant value. This makes it an ideal choice for applications where a stable voltage is needed.This polyphase synchronous buck regulator has two integrated N-channel MOSFETs and is capable of providing output current of up to 25A. It has a typical internal dropout voltage of 0.8V at 25A of continuous output current. The operating temperature range for this voltage regulator is between -40 and +125°C. Furthermore, its input voltage can range from 7.5 to 28V. The LD2981ABM38TR also has an on-board over current protection with threshold up to 35A.The LD2981ABM38TR is well suited for a wide range of applications, such as those that require high current, low voltage, and reliable performance in automotive, industrial, and communications systems. It is especially suitable for applications that involve power distribution in space-constrained areas. Additionally, the LD2981ABM38TR can be used in switch-mode power supplies and even as an adjustable voltage regulator in portable communication devices.The working principle of the high-power buck regulator is simple. The regulator is provided with an input voltage (Vin) and an output voltage which is regulated to a constant value. The power rating of the regulator determines the maximum output current and the maximum input voltage. The regulator uses an N-channel MOSFET to turn the power switch on and off in a synchronized manner.When the voltage across the power switch is less than the output voltage, it turns on and supplies a regulated current to the output. As the output voltage increases, the power switch will turn off. This causes the output voltage to drop and the regulator will start to regulate the output voltage back to the required value.The LD2981ABM38TR is designed to ensure reliable and stable operation, with the added advantages of efficiency and low noise. Its high output current and input voltage ranges makes it suitable for a variety of applications. Also, the integrated over-current protection provides added safety and performance. These features make the LD2981ABM38TR a great value for many different applications.The specific data is subject to PDF, and the above content is for reference
