Working Principles

The MAX6043CAUT33#TG16 is a linear regulator that regulates the output voltage to a constant level, regardless of changes in the input voltage or load conditions. It achieves this by using a pass transistor and feedback circuitry to maintain a stable output voltage.

When the input voltage (VIN) is within the specified range, the regulator provides a regulated output voltage (VOUT) of 3.3V. The feedback pin (FB) monitors the output voltage and adjusts the pass transistor accordingly to maintain the desired voltage level.

The enable pin (EN) allows for easy control of the regulator's on/off state. When EN is high, the regulator is enabled, and when it is low, the regulator is disabled, reducing power consumption.
