Working Principle
The RT9068-33GFP Linear Voltage Regulator is based on the Linear Regulator topology. It uses a voltage reference and an operational amplifier to provide an adjustable output voltage that is proportional to its input voltage. The operational amplifier compares the reference voltage to the output voltage via a feedback loop. When the feedback voltage becomes too low, the amplifier turns on the voltage regulator to increase the output voltage to the target value. The regulator operates in linear mode to maintain the output voltage while using power components such as a transistor as a switch at low duty cycle to regulate the output voltage. During this process, the device uses energy from the input voltage to create the required output voltage with minimal power loss.
Conclusion
The RT9068-33GFP is a Linear Voltage Regulator manufactured by Richtek. It is a single output voltage regulator with a wide input voltage range of 4.5V~33V and adjustable output voltage range of 0.8V to 20.5V. With its high efficiency rating, low noise, low output voltage drop, adjustable current limit of up to 3.3A and reverse current protection, the RT9068-33GFP is an ideal device for automotive and industrial applications. It is suitable for applications where safe and reliable power delivery is needed.
