NJM2880U21-TE1# is an integrated low-dropout (LDO) linear regulator outputting an adjustable output voltage that is ideally suited for low noise and low power applications, such as battery powered electronic devices, peripheral devices, and digital logic ICs. The integrated design of the NJM2880U21-TE1# helps to conserve board space, improve efficiency, and reduce the number of external components.

The NJM2880U21-TE1# low-dropout, linear regulator offers a 1.8V to 5.0V voltage output range, adjustable via an external resistor divider. It also features an on-off control pin that allows the user to power down the device when not in use.

The NJM2880U21-TE1# provides a full range of features that make it an ideal choice for small form factor applications. These features include low quiescent current and low dropout voltage, current limit protection, reverse current protection, thermal shutdown, and 75mV output voltage ripple. Additionally, the device is designed with an amplifier that can provide up to 1.5A of continuous load current.

Applications for the NJM2880U21-TE1# include cell phone power supplies, portable chargers, digital cameras, digital video recorders, digital music players and any other low-power portable electronic device. In addition, it can be used in automotive applications and other industrial applications that require a cost-effective, low-power solution.

The NJM2880U21-TE1# linear regulator works by connecting an input voltage to the device and then connecting a resistor divider to the output. When the input voltage is higher than the desired output, a pass element (commonly known as a pass transistor) is turned on and supplies current to the output resulting in a voltage drop across the pass element\'s resistance. This voltage drop is regulated and adjusted with the resistance of the resistor divider to achieve the desired output voltage.

The output voltage is further regulated using a pair of error amplifiers. These error amplifiers track the output voltage and compare it to the reference voltage developed by the resistor divider. If the output voltage drops below the reference voltage, the error amplifier increases the gate voltage of the pass element, which increases the current supplied at the output. Conversely, if the output voltage exceeds the reference voltage, the error amplifier decreases the gate voltage of the pass element, resulting in a decrease in current supplied at the output.

In summary, the NJM2880U21-TE1# linear regulator is designed to provide a low-power, cost-effective solution for a wide range of applications requiring stable output voltage with low noise. One of its main advantages is its high efficiency, as well as its small form factor. Additionally, it offers a range of features to help protect the IC from damage due to excessive current and temperature.
