Working Principle

The LT3984IBP-2.0/NOPB is a linear voltage regulator, which means it operates in a linear mode. This means it is based on a voltage feedback loop, which adjusts its internal output voltage based on the input voltage level.In order to regulate the voltage level, the regulator first compares the voltage output against the reference voltage at its output terminal. If the voltage output is too high, the regulator then adjusts the gates of its transistors to reduce the current output, and vice versa. This creates a feedback loop which brings the output voltage in balance with the reference voltage.The LP3984IBP-2.0/NOPB also comes with an internal error amplifier, which provides the regulator with more accuracy and sensitivity. The amplifier compares the voltage output levels across the resistor in the feedback loop, and any discrepancies are immediately corrected by adjusting the current output.The LP3984IBP-2.0/NOPB is highly effective at keeping the output voltage stable regardless of fluctuating load or input voltages. In addition, its low power consumption and small size make it an attractive option for portable electronics. Its extended temperature range and high level of accuracy and reliability also make it a great choice for industrial, automotive and medical applications.
