Introduction to LK112M13TR The LK112M13TR is a linear voltage regulator integrated circuit (IC) manufactured by LK electronics. This IC is used in both industrial and consumer applications, as well as in automotive industries. It is also known as an LDO (low dropout) regulator and is used to supply a steady and reliable voltage to an electronic circuit. It features an adjustable output from 1.5V to 13.5V, making it well suited for a variety of applications such as computer motherboards, television sets, portable electronics devices, and many more.Features of the LK112M13TRThe main features of the LK112M13TR include its wide input range (4.5V to 36V), high accuracy, and low noise. It also has an adjustable output voltage of 1.5V to 13.5V. Additionally, this IC is capable of supplying current up to 1000 mA. It is a monolithic integrated circuit with low quiescent current, making it a great choice for battery-powered devices. The device is also protected against reverse polarity and output current overloads. Furthermore, the device is CEC compliant, meaning it meets energy efficiency standards and helps to reduce energy consumption. Application fields and working principle of the LK112M13TRThe LK112M13TR is widely used in consumer electronics, industrial, automotive and portable electronics applications. Its adjustable output voltage and low noise make it well suited for powering digital circuitry. Additionally, it can be used to power audio amplifiers, cell chargers, LED drivers, and more. Many consumer electronics such as mobile phones, digital cameras, and laptops also use this voltage regulator.The working principle of the LK112M13TR is based on the series voltage regulation theory, which requires that the output voltage be proportional to the input voltage. The output voltage is regulated by controlling the current into the voltage regulator\'s reference terminal. The reference voltage is compared to the feedback voltage (output voltage) through a differential amplifier, and the difference is used to drive an error voltage that is responsible for controlling the output voltage. Every time the output voltage deviates from its predetermined value, the error voltage is adjusted, thereby controlling the output voltage.ConclusionThe LK112M13TR is a versatile and highly reliable linear voltage regulator IC suitable for a variety of applications. It has a wide input range and features a low-noise output, high accuracy, and current protection of up to 1000mA. It is CEC compliant, making it suitable for energy-saving applications. Additionally, the working principle of this device is based on the series voltage regulation theory that helps to accurately regulate the output voltage.
