The LDK120C18R is a linear voltage regulator specifically designed for device protection in system applications such as automotive, industrial and consumer electronics. This device is built using high-grade bipolar transistors, MOSFETs, and linear voltage regulators.

The LDK120C18R is capable of providing up to 18V of output voltage with a maximum load current of 12 A. It also features an adjustable output voltage and current limit, as well as an adjustable input voltage range. This device also has an adjustable over-temperature shutoff that can be adjusted for a variety of temperatures.

The LDK120C18R’s application fields can vary extensively and include computers and communications, lighting, consumer products, process control, power supplies, battery chargers and automotive applications. In addition, this device can be used for power-conversion tasks, such as battery voltage boosting, voltage boosting from batteries, current limiting, and other protective functions.

This device is a linear voltage regulator, typically used to provide a steady output voltage from an input voltage range of 5.5±0.8V to 15.5V. It is designed to provide a regulated current output, ensuring that the device load receives the correct amount of electrical power. In this case, the current output is determined by the user’s application and the power supply design.

The linear voltage regulator works by monitoring and comparing the output voltage to a reference voltage produced by a band-gap voltage reference. The comparison is done using an op-amp, which will detect a voltage difference and try to correct it by controlling a pass transistor. This pass transistor is configured to either pass or reduce the input current, thus adjusting the output voltage.

By controlling the pass transistor, the linear voltage regulator is able to maintain a constant output voltage, regardless of loading fluctuation or changes in the input voltage. This is especially important for devices such as motor controllers or microprocessors, which need a consistent and reliable voltage supply for proper functioning.

The LDK120C18R also incorporates several safety features, including short-circuit and over-temperature protection, as well as an adjustable current limit. These safety features are designed to ensure that the device will not be damaged or malfunction due to improper operation. This device is also designed to be EMC compatible and meets all the applicable EMC standards.

The LDK120C18R is a linear voltage regulator designed to provide a steady output voltage in a variety of applications. Its adjustable input and output voltages, adjustable current limit, and safety features make it suitable for a wide range of applications, including automotive, industrial, and consumer electronics.
