Working Principles

The MAX6313UK33D1-T is a linear voltage regulator that utilizes a pass transistor to regulate the output voltage. It operates by comparing the feedback voltage (FB pin) with an internal reference voltage, adjusting the pass transistor to maintain a stable output voltage. The enable (EN) pin controls the regulator's on/off state.
