Working Principles

The LT3083EDF#PBF operates based on the principle of linear voltage regulation. It uses a pass transistor to regulate the output voltage by adjusting the resistance between the input and output pins. The ADJ pin allows the user to set the desired output voltage by controlling the feedback loop.

When the input voltage is higher than the desired output voltage, the pass transistor adjusts its resistance to maintain a stable output voltage. Conversely, if the input voltage drops below the desired output voltage, the pass transistor increases its resistance to compensate and maintain the desired voltage level.
