Working Principles

The TPS2211APWR operates as a low dropout voltage regulator by comparing the feedback voltage (FB) with a reference voltage. It adjusts the pass transistor's resistance to maintain a stable output voltage, even when the input voltage varies.

When the enable pin (EN) is high, the IC is active, and it regulates the output voltage according to the feedback voltage. If the input voltage drops below the desired output voltage plus the dropout voltage, the regulator enters dropout mode, where the pass transistor operates in its linear region to maintain the output voltage.
