Working Principles

LM9036DT-3.3/NOPB operates as a linear voltage regulator. It regulates the output voltage by comparing it to an internal reference voltage. When the input voltage exceeds the desired output voltage, the regulator adjusts its internal circuitry to reduce the output voltage. Conversely, if the input voltage drops below the desired output voltage, the regulator compensates by increasing the output voltage. This feedback mechanism ensures a stable output voltage of 3.3V.
