Working Principles
The LT3092EST is a linear voltage regulator that operates by maintaining a constant voltage difference between the input and output pins. It uses a feedback mechanism to adjust the output voltage based on the voltage divider network connected to the ADJ and FB pins.
When the input voltage exceeds the desired output voltage, the regulator reduces the voltage across its internal pass transistor, ensuring a stable output voltage. Conversely, if the input voltage drops below the desired output voltage, the regulator increases the voltage across the pass transistor to maintain the desired output voltage.
