Working Principles

The NCV8405STT1G operates as a linear voltage regulator. It regulates the output voltage by maintaining a constant voltage drop across its internal pass transistor. This ensures that the output voltage remains stable even when the input voltage fluctuates.

When the enable pin (EN) is high, the IC is active, and the output voltage is regulated according to the desired value set by the external resistors. If the enable pin is low, the IC enters a low-power standby mode, reducing the quiescent current to conserve energy.
