Working Principles

The MAX802LCSA+T is a linear voltage regulator that uses a pass transistor to regulate the output voltage. It operates by comparing the feedback voltage (FB) with a reference voltage, and adjusts the pass transistor accordingly to maintain a stable output voltage. The enable pin (EN) controls the regulator's on/off state, while the bypass capacitor (BYP) improves stability and transient response.
