LD39150DT12-R is a three-terminal adjustable regulator primarily intended for use in TVs, DVD players and other audio/video appliances. It provides an excellent line and load regulation and uses current limited and thermal protection against current overloads. The LD39150DT12-R application field and working principle mainly concerns voltage regulation.

Overview of LD39150DT12-R

The LD39150DT12-R offers an on/off feature with an input control voltage of 2.25V to 7.5V for enabling and disabling the device as well as output voltage adjustments of up to 5.6V. It offers a low dropout voltage and low output noise, and can supply up to 150mA of output current. The device also offers a wide range of current limit settings and requires very few external components. This makes it particularly suitable for low input voltage, low quiescent current and low output voltage applications.

In order to control the output voltage and provide excellent line and load regulation, the device utilizes an internal temperature-compensated reference, current limit and thermal shutdown protection. This ensures that the device can provide excellent performance over a wide temperature range, allowing it to produce an output voltage that is resilient to external influences.

Operating Principle of LD39150DT12-R

At the heart of the LD39150DT12-R is an internal control circuit that monitors the output voltage and adjusts it as necessary. This circuit works on the principle of feedback, meaning it adjusts the output voltage based on the difference between the output voltage and the reference voltage. This ensures that the output voltage remains relatively constant, regardless of the input voltage and load.

The device also contains a current limit circuit that monitors the output current and limits it as necessary. This prevents excessive current draw in overload conditions and helps protect the device from overheating. In addition, the Tri-level Thermal Shutdown circuit monitors the temperature of the device and shuts down the output if it exceeds a certain temperature, thus preventing permanent damage due to overheating.

Applications of LD39150DT12-R

The wide range of input voltage, low quiescent current, low dropout voltage and excellent performance over a range of temperatures make the LD39150DT12-R suitable for a wide range of applications. It is primarily used as a voltage regulator in TVs, DVD players, and other audio/video appliances. It can also be used in a variety of other applications requiring efficient voltage regulation, such as automotive and industrial equipment.

Since it requires very few external components, it is particularly suitable for low voltage, low current, and low output applications. Additionally, the Tri-level Thermal Shutdown circuitry and the output current limit features make the LD39150DT12-R well-suited for applications that require robust protection from overheating and overloads.
