Working Principle

AS13985H-30-T regulator is based on a linear voltage regulator design. It utilizes a series of pass transistors to achieve its voltage regulation. The output voltage of the series of transistors is always in a steady state and remains constant, regardless of temperature, humidity, or other operating conditions. The regulator works by controlling the emitter current of the pass transistors and sensing errors in the output voltage. If there is an increase or decrease in output voltage, the current is adjusted to maintain the desired output voltage.

The AS13985H-30-T voltage regulator uses a number of feedback mechanisms to ensure that it is always providing the correct voltage. It utilizes on-chip voltage references and error amplifiers to sense fluctuations in the output voltage. It also uses internal circuitry to sense the temperature and adjust the output voltage accordingly. The regulator\'s overvoltage protection feature ensures that the output voltage does not go above the specified limit, and its thermal shutdown feature prevents the IC from overheating and damaging itself.

In summary, the AS13985H-30-T is a reliable and high-performance linear voltage regulator that provides a constant and stable output voltage for various industrial, medical, and automotive design applications. Its wide input voltage range, high current output, and low-output noise makes it ideal for use in complicated designs. Additionally, it provides a number of protection features, such as overvoltage and thermal protection, to ensure the reliability and longevity of applications.
