Working Principles

The MAX6887IETE+T is a low dropout voltage regulator that regulates the output voltage based on the feedback received from the FB pin. It compares the feedback voltage with an internal reference voltage and adjusts the pass transistor accordingly to maintain the desired output voltage. The EN pin enables or disables the regulator, while the SS pin controls the soft-start feature to minimize inrush current during startup.
