The working principle underlying the BD15HA3MEFJ-ME2 device consists of two main elements: a voltage reference, and an error amplifier. The voltage reference is a voltage regulator per se that is responsible for setting a precise output voltage when the input voltage is within the correct range. This reference voltage is then compared to the output voltage and the difference is amplified by the error amplifier, which works as a feedback loop. This feedback loop is responsible for controlling the output voltage and keeping it precision stable even as the input voltages change.

The BD15HA3MEFJ-ME2 is a versatile device that provides reliable and accurate voltage regulation for a variety of automotive applications. Its low quiescent current, adjustable output voltage, and low-noise operation make it an ideal choice for powering automotive electronic devices. Additionally, its high operating temperature range, thermal protection, and current limiting feature make it a safe and reliable regulator for a variety of automotive applications.
