Introduction to LK112M38TR

The LK112M38TR is a linear regulator, commonly referred to as a PMIC (power management integrated circuit) for managing and regulating power voltages. It is a positive voltage regulator which is designed for fixed voltage and current limitations from an input voltage supply. This device is used in a variety of applications but is especially useful for powering automotive applications and industrial embedded systems.

Application Field and Working Principle

The LK112M38TR is used primarily in automotive and industrial systems. This regulator provides a smooth and accurate output voltage across a wide input voltage range which is ideal for automotive applications as well as industrial applications. This device is also used in safety-critical operations where voltage regulation needs to be precise, such as medical and avionic systems.

The working principle of the LK112M38TR is similar to most other linear regulators. It is based on the primary voltage applied to the regulator being higher than the output voltage. The regulator then reduces the current by varying the resistance in the device, thus regulating the voltage. This method is sometimes referred to as linear regulation.

The LK112M38TR has a band-gap reference circuit which is used to accurately determine the output voltage from the input voltage. This method of voltage regulation maximizes efficiency and minimizes heat generation in the device. The output voltage is also monitored by an enable control pin which can be used to enable or disable the regulator based on the required voltage.

The LK112M38TR can also be configured as an adjustable regulator by adding external resistors across the appropriate pins. This allows for a variable output voltage to be achieved within certain limits. The device also offers protection against short-circuits, over-currents and over-temperatures.

The operating temperature range of the LK112M38TR is 0°C to +70°C, and the total power dissipation is 4 Watts. The device also offers protection against voltage surges up to 40V, making it an ideal component for many industrial applications.

Conclusion

The LK112M38TR is a positive linear regulator that is designed for fixed voltage and current limitations from an input voltage supply. This device is used mainly in automotive and industrial applications, and offers a wide input voltage range and smooth and accurate output voltage. It is also capable of being configured as an adjustable regulator and offers protection against short-circuits, over-currents and over-temperatures.
