3. Reverse Current Protection: The IC incorporates reverse current protection, preventing any backflow of current from the output to the input side.

4. Short-Circuit Protection: In case of a short circuit on the output side, the TPS2061CDBVR limits the current to protect both the IC and the connected components.

Advantages and Disadvantages

Advantages

• Wide input voltage range allows compatibility with various power sources.
• Low quiescent current minimizes power consumption during standby or idle states.
• Fast transient response ensures stability during load changes.
• Thermal shutdown protection prevents overheating and damage to the IC.

Disadvantages

• Maximum continuous output current limited to 500mA, which may not be sufficient for high-power applications.
• Dropout voltage of 200mV at 100mA may cause a slight voltage drop across the IC.

Working Principles

The TPS2061CDBVR operates as a linear voltage regulator. It regulates the output voltage by adjusting the resistance between the input and output pins based on the feedback received from the output voltage. This feedback loop ensures that the output voltage remains constant even when the input voltage or load conditions change.
