This voltage regulator can be used to provide a stable supply for processors, memory, or any other devices requiring a stable voltage and precise current.
Working Principle of LF25CDT-TRY
The LF25CDT-TRY is based on a linear topology, which utilizes an output transistor to adjust the output voltage according to an internal reference voltage. The output voltage is set by an external resistor divider connected between the output terminal and ground. The output voltage is then further stabilized by the internal error amplifier circuit. The error amplifier senses the output voltage and compares it to the internal reference voltage. The difference voltage signal is then fed back to the output transistor to control the output voltage. The internal control circuit also includes transistors, resistors and capacitors to provide clear signal and prevent possible noise interference. It also provides wide dynamic range, good frequency response, and higher accuracy.
The LF25CDT-TRY provides a high-efficiency power supply solution that is easy to use due to its high stability performance. It has over-voltage, under-voltage and short-circuit protection to minimize risk of fault. The output can be adjusted from 1.1 to 33V, making it ideal for various applications. It offers ripple rejection ranging from 70dB up to 100dB depending on the operating conditions, making it an ideal choice for low-noise and low-distortion power supplies.
In conclusion, the LF25CDT-TRY is a linear type PMIC (Power Management Integrated Circuit) voltage regulator suitable for a wide range of applications. Its wide voltage range, high efficiency, high accuracy and high stability make it an ideal solution for various situations. Moreover, its features such as over-voltage protection, under-voltage protection and short-circuit protection makes it an ideal choice for various applications.
