Working Principles

The MAX5003CEE+ operates as a linear voltage regulator. It takes an input voltage from the Vin pin and regulates it to a stable and adjustable output voltage at the Vout pin. The feedback (FB) pin is used to set the desired output voltage by connecting external resistors. The enable (EN) pin controls the on/off state of the regulator.

When the input voltage exceeds the desired output voltage, the MAX5003CEE+ enters a dropout mode, where it maintains a constant output voltage despite a decreasing input voltage. This feature ensures proper functionality even when the power supply is not perfectly regulated.
