Working Principles

The MAX5903NNEUT+T is a voltage regulator that provides a stable output voltage within a specified range, regardless of variations in the input voltage. It achieves this by employing a feedback mechanism that continuously adjusts the internal circuitry to maintain the desired output voltage.

When the enable pin (EN) is set high, the regulator starts operating and regulates the output voltage based on the feedback received from the FB pin. The power good (PG) pin indicates whether the output voltage is within the acceptable range.
