The NJU7201L2-12 has an input voltage range of 6V to 40V and is protected against excessive input voltages. The device can handle output currents up to 100mA and is also protected against excessive output currents. The IC also has a power-on reset (POR) feature, which ensures that the device always starts at the reference voltage.

The NJU7201L2-12 has an adjustable output voltage range of 1.2V to 24V, making it suitable for power supply designs for a variety of applications. Its high efficiency and low quiescent current makes it an attractive solution for power supply designs for consumer electronics applications and other high-efficiency, low-power applications. The tight regulation facilitates the use of this device in applications where noise and ripple need to be minimized.

The working principle of the NJU7201L2-12 is based on the fact that when a current flows through a resistor, a voltage drop is produced across it. The NJU7201L2-12 uses this fact to produce a regulated voltage output. The device consists of an internal voltage reference, an error amplifier, a voltage divider, and a pass transistor.

The internal reference voltage is compared with the voltage across a voltage divider connected to the device’s output. When the two voltages become equal, the device turns off the pass transistor and an output voltage is obtained. The output voltage can be adjusted by adjusting the resistance of the voltage divider. This allows the output voltage to be precisely regulated.

In summary, the NJU7201L2-12 is a low-capacity, low-power, linear voltage regulator IC designed for industrial, computer, telecommunications, and consumer electronics applications. It has a wide input voltage range and can handle output currents up to 100mA. It has two adjustable outputs, one of which is adjustable by a resistor voltage divider, and it works on the principle of a comparison between an internal reference voltage and a voltage across a resistor voltage divider.
