Working Principle
The RT9161A-28GV is designed to provide a regulated DC voltage from a wide range of input voltages (7-25V). This is done using a high-gain voltage-level-shifter circuit, which operates as a linear regulator.The voltage-level-shifter works by using an external resistor to set the required output voltage. This resistor forms part of a feedback loop which compares the output voltage with the reference voltage. When the output voltage differs from the reference voltage, the linear regulator will adjust the output voltage to make sure it’s at the desired level.In order to maintain a consistent output voltage, the RT9161A-28GV has an internal power supply rejection ratio voltage which is set slightly higher than the output voltage. This prevents any changes in the input voltage from affecting the output voltage.The RT9161A-28GV also has a thermal shut down protection, which triggers when the internal temperature reaches a certain threshold. This helps to keep the device cool, and also helps to prevent any damage caused by excessive heat.Conclusion
The RT9161A-28GV is a versatile Linear regulator IC which can be used in a wide range of applications. It features a wide operating range for its 7-25V input voltage, with a maximum output current rating up to 1 A. It is designed to maintain a consistent output voltage, thanks to its high-gain voltage-level-shifter circuit, and its internal power supply rejection ratio voltage. It also has thermal shut down protection, which helps to protect the device from excessive heat.The specific data is subject to PDF, and the above content is for reference
