Working Principles

The S-1003NA25I-M5T1U operates as a linear voltage regulator. It uses a pass transistor to regulate the output voltage based on the input voltage and a feedback mechanism. When the input voltage exceeds the desired output voltage, the pass transistor reduces its conductivity, reducing the output voltage. Conversely, when the input voltage drops below the desired output voltage, the pass transistor increases its conductivity, raising the output voltage.
