LM250K Datasheet/PDFThe LM250K is a linear voltage regulator integrated circuit (IC) which is exclusively designed for power management applications. This voltage regulator consists of many essential features such as inrush current limiting, soft-start, pulse-by-pulse current limit, output voltage regulation, over-voltage protection, thermal shutdown protection, and over-current protection which makes this IC ideal for use in a variety of power management applications. This voltage regulator is typically used in laptops, desktop computers, external power supplies, and other consumer appliances to provide a reliable and accurate voltage to ensure a stable electricity supply.
Features of the LM250K
The LM250K is a highly efficient and effective linear voltage regulator which offers a variety of features that make it ideal for use in a range of power management applications. It offers up to 3.3 A continuous output current and has a voltage drop of only 15 mV at full load to ensure a better power efficiency and improved output efficiency. It also offers inrush current limiting and thermal shutdown protection which helps to protect the IC from dangerous over-current events. It has a very low output voltage noise and ripple which aids in better signal fidelity. This IC also features excellent output voltage regulation, over-voltage protection, and soft-start functionality as well as an adjustable over-current protection.
Working of the LM250K
The LM250K employs a fixed voltage, linear regulation scheme. This scheme works in a very simple way, wherein the input voltage is ramped up or down to the fixed voltage level set by the user. As its name suggests, the LM250K operates on a linear basis, which means that it follows a linear path from input to output. This reduces power losses compared to other types of voltage regulation. When the output voltage drops below the required level, the LM250K removes the excess charge and adjusts the current accordingly. On the other hand, when the output voltage is higher than the required output voltage, the LM250K follows a separate control loop and applies a corresponding reducing current to reduce the output voltage.
Application Fields of the LM250K
The LM250K is a very reliable and efficient linear voltage regulator which finds use in various consumer and industrial applications. It is typically used in laptops, desktop computers, external power supplies and other consumer appliances such as refrigerators and gaming consoles. It is also used in precision medical instrumentation and medical imaging devices, specialized motor control systems, signal conditioning and laboratory test equipment, industrial batteries and chargers, telecommunication systems and various other applications.
