The LF85CDT-TR is a fully integrated voltage regulator of the linear type. It is a versatile single channel device that can be used for a variety of applications, providing constant output voltage with good line and load regulation.

The LF85CDT-TR voltage regulator is designed with a wide input voltage range letting it be deployed in a variety of environment. The input voltage can go from 4V to 40V while the output voltage can go from 5V to 40V, allowing it to be used in a wide range of applications.

The LF85CDT-TR voltage regulator provides good line and load regulation. The output voltage changes relatively little when the load and the input voltage vary. This tight regulation is important in all applications where having a stable output voltage is essential.

The LF85CDT-TR also has a good ripple rejection ratio, resulting in a good quality output voltage with minimal distortion. This is especially important when the regulator is used with audio and other sensitive applications.

The LF85CDT-TR features a low "ON" resistance due to its high MOSFET transistor design, which allows the device to deliver up to 4A of current with minimal losses.

The LF85CDT-TR also has a built-in thermal protection circuit, which will shut down the regulator if the temperature exceeds a certain limit, thus preventing any damage and prolonging the life of the device.

The LF85CDT-TR is a reliable and efficient voltage regulator suitable for a wide range of applications, from audio, to industrial and automotive.

The working principle of the LF85CDT-TR is quite simple. The device consists of two main components: a voltage reference and an error amplifier, both of which are used for voltage regulation.

The voltage reference is an internal precision voltage reference, whose output is compared to the output of the error amplifier. The voltage reference provides a stable voltage to the error amplifier and is used as the reference point for the output voltage.

The error amplifier is connected to the output of the voltage regulator and compares the output voltage to the voltage reference. Depending on the comparison result, the error amplifier will adjust the output voltage accordingly in order to maintain a stable output voltage.

The output voltage can also be adjusted using an external control voltage, allowing the voltage regulator to be used in adjustable applications.

Overall the LF85CDT-TR is a versatile and reliable voltage regulator with a wide input voltage range and good line and load regulation, making it suitable for a variety of applications.
