The LM140LAH-12/NOPB is a linear voltage regulator, which is a type of electrical power regulator that provides a steady output voltage, despite fluctuations in the input voltage, load current or temperature. This voltage regulator can be found in a wide variety of applications, with automotive, industrial and consumer electronics being just a few of these. To better understand the LM140LAH-12/NOPB and its use, it is necessary to understand its working principle, application field and features.

The Working Principle of the LM140LAH-12/NOPB

The LM140LAH-12/NOPB is an adjustable linear voltage regulator which uses a series of diodes and transistors to regulate the input voltage and provide an output voltage regulated to the required voltage level. This is done by the use of a built-in feedback loop, which compares the regulated output voltage with an internal reference. This reference is then adjusted to maintain the stability of the output voltage. As the load current increases, the voltage regulator automatically increases the output voltage to compensate for the increased current.
