Working Principle
The NCV4269DWR2G is a linear voltage regulator that provides a fixed output voltage. It operates by controlling the input voltage through a feedback loop. The current is limited by an external resistor. The device has an internal P-channel MOSFET that acts as a pass transistor to connect the input voltage to the output. This pass transistor is driven by an error amplifier and is designed to maintain the output voltage at a constant level. The output voltage is determined by the feedback network of the device. The output voltage is further regulated by the Adjust pin, which is used to adjust the output voltage to the desired level. The current limit is determined by the current sense resistor. In the case of an overcurrent condition, the current is limited by the internal circuitry. The device also includes short circuit and thermal overload protection. This protection circuit monitors the output voltage and if it exceeds the limits, the output is shut off or interrupted until the fault is removed.
