Working Principle

The TPS73433TDDCRQ1 is an adjustable linear voltage regulator intended to deliver a controlled voltage that is higher than the input voltage. It works by comparing the output voltage to a voltage reference, and then providing an error signal to the pass transistor in order to adjust the output voltage to the required value. The error signal is used to drive the pass transistor into saturation or cut-off, to ensure that the output voltage remains constant, even under dynamic load conditions. The error amplifier compares the output voltage with the internal reference voltage, and the resultant change in error voltage is used to adjust the base drive. The pass transistor, along with the other components of the voltage regulator, forms a closed-loop control system which adjusts the output voltage based on the internal reference voltage.
