LD39150DT25-R is a three terminal low dropout linear voltage regulator that features 200mA of output current, low dropout voltage, accurate output voltage, current overload and thermal shutdown. The device is designed with a TTL compatible output state and further enhanced with reverse battery protection. In addition, the device is capable of voltage supervision with low quiescent power and is easy to implement.
The LD39150DT25-R is available in a TO-243AA (SMT-4) package and the output voltage of the device can be adjusted from 2.50V to 5.50V. The device is suitable for use in systems where a stable output voltage is required, such as general purpose, microcontrollers and automotive applications. The LD39150DT25-R is available in both commercial and industrial temperature ranges.
The LD39150DT25-R is designed to provide the highest level of performance and reliability. By using advanced design techniques and optimizing the integrated circuitry, the device offers superior control over output voltage stability and current regulation while also exhibiting improved reliability and greater protection against power surges. The device is designed to provide a constant output current and adjust to fluctuations in input voltage, making it ideal for applications in which the supply voltage is unstable.
The LD39150DT25-R has a wide range of applications where the stability of the output voltage is critical, such as for driving logic devices and LCDs. It can also be used in various design configurations such as a single power supply, dual power supply, and multiple power supply configurations. Its small package size and low dropout voltage characteristics make it ideal for use in space constrained environments and applications with a wide range of supply voltage requirements.
The working principle of LD39150DT25-R is based on the well-known error amplifier control circuit. The output voltage of this device is regulated by the error amplifier which compares the reference voltage to the output voltage and produces an output signal to the transistor (pass element) to adjust the output voltage. The magnitude of the output voltage is determined by the magnitude of the reference voltage provided on the Amplifier Control pin. The output voltage is further stabilized by the stabilizing capacitor which is connected between the output of the pass element transistor and the output terminal and will maintain the output voltage during brief periods of over/under load conditions.
In conclusion, the LD39150DT25-R from Diodes Incorporated is a low-dropout linear voltage regulator that provides excellent load and line regulation with accurate output voltage and current. This linear voltage regulator operates from a range of 2.50V to 5.50V, ensuring a stable regulated output voltage that is suitable for many applications. Its wide range of applications and superior performance make it an ideal choice for many different projects.
