Working Principles

The NCV33064D-5R2 operates as a linear voltage regulator. It uses a pass transistor to regulate the output voltage based on the difference between the input and desired output voltage. The adjustable output voltage feature is achieved by using a feedback mechanism that controls the pass transistor's conduction.

When the input voltage exceeds the desired output voltage, the pass transistor reduces its conduction, resulting in a lower output voltage. Conversely, when the input voltage drops below the desired output voltage, the pass transistor increases its conduction, maintaining a stable output voltage.
