The L4931CPT80-TR is a cost-efficient monolithic integrated circuit voltage regulator specifically made for the low-dropout linear applications. This high performance voltage regulator come with a range of output current up to 200mA, enabling it to be used as an adjustable regulator, or a fixed regulator to achieve a stable output voltage. This device is particularly useful in a wide range of applications that includes handheld, laptop and desktop PCs, gaming systems, networking equipment, automotive, consumer electronics, along with many other consumer and industrial applications.

The L4931CPT80-TR is comprised of a voltage reference and two series pass transistors, in addition to protective circuitry. Together, these components provide a constant output voltage with a load regulation between 0.01V and 0.04V and a standard line regulation of 0.02V. The device also features very low output noise, which is typically less than 50μV in most applications.

The device works via an internal voltage divider consisting of two resistors. The internal pass transistor provides a feedback loop that allows it to adjust the current according to changes in the input voltage. This ensures that the output voltage remains stable, even under varying input voltage.

The L4931CPT80-TR also includes several other features such as over current protection, thermal protection, and short circuit protection, which help to ensure reliable operation and protection of the device. Additionally, the device includes an optional shut off feature, which allows it to be completely disabled when not in use.

The L4931CPT80-TR requires very few components to be implemented. The device is designed in a very small 4.2mm x 4.2 mm DIP package, making it easy to integrate into any design and reduce the overall system size.

In conclusion, the L4931CPT80-TR is a reliable and cost-efficient voltage regulator. Its combination of performance and features makes it an ideal choice for a wide range of low dropout linear applications. The device’s small size and low component count make it easy to integrate into existing designs, or to develop a new system. With its protection features and ability to provide a very stable output voltage, the L4931CPT80-TR is an excellent choice for a range of applications.
