Working Principles

The TPS2830DRG4 operates as a linear voltage regulator. It regulates the output voltage by comparing the feedback voltage (FB) with a reference voltage. The enable pin (EN) controls the operation of the regulator. When EN is high, the regulator is enabled, and it starts regulating the output voltage based on the feedback received. If EN is low, the regulator is disabled, and the output voltage is not regulated.
