Working Principles

The LTC1530CS8-2.5#TRPBF operates as a linear voltage regulator. It regulates the output voltage by maintaining a constant voltage drop across its internal pass transistor. When the input voltage is higher than the desired output voltage, the pass transistor remains in the "on" state, allowing current to flow from the input to the output. As the input voltage decreases, the dropout voltage increases, but the regulator compensates to maintain the desired output voltage.
