Working Principle

AP131-20YL-13 works by using the basic principles of a linear voltage regulator. It consists of a power transistor which is connected to a reference source, the output voltage is derived from the reference source with the help of feedback circuitry. The power transistor acts as a variable resistance controlled by the feedback circuit and is used to limit the voltage at the output. The feedback circuit compares the output voltage with the reference source and controls the transistor to maintain a constant output voltage.

When the output voltage exceeds the reference voltage, the voltage drop across the power transistor decreases and the output voltage is pulled to the same voltage as the reference source. Conversely, when the output voltage is lower than the reference voltage, the voltage drop across the power transistor increases, limiting the current through it and pulling the output voltage to the reference voltage.

The AP131-20YL-13 is designed to be easy to use and highly efficient, reducing power loss and power dissipation for long battery life. It is also designed to operate over a temperature range of -40°C to +85°C, making it ideal for applications in industrial and automotive environments. Additionally, the linear regulator also provides over-current, over-voltage and short-circuit protection, making it an ideal power management solution for many applications.

The AP131-20YL-13 is a high performance linear voltage regulator which is able to provide a reliable and efficient power solution for many applications. It is a great solution for industries such as consumer, industrial and automotive electronics, providing a reliable and cost effective power solution.
