Working Principles
The TPS2223APWPRG4 operates as a low-dropout voltage regulator. It regulates the output voltage by maintaining a constant voltage difference between the input and output terminals. This is achieved through a feedback mechanism that adjusts the internal pass transistor's resistance to maintain the desired output voltage.
When the input voltage drops below the desired output voltage, the regulator increases the resistance to compensate and keep the output voltage stable. Conversely, if the input voltage exceeds the desired output voltage, the regulator reduces the resistance to maintain the desired output voltage.
