It also includes a power-on reset circuit, which monitors the input voltage to guarantee a safe startup. Broadly, the LP3882EMR-1.2/NOPB is classified as a PMIC (Power Management IC) in the Voltage Regulators category under Linear.

LP3882EMR-1.2/NOPB Application Field and Working Principle

The LP3882EMR-1.2/NOPB is used in any application where a low dropout voltage regulator is required to maintain a constant and steady output. Common applications include computer systems, automotive, telecommunication and other audio/video products. This device can be used in place of a fixed voltage or adjustable linear regulator, allowing for greater flexibility in design.

This device is a linear three terminal regulator, which uses a voltage reference and an operational amplifier to maintain an output voltage that is proportional to the reference voltage. The voltage reference contains two transistors, connected in a Darlington pair configuration. As the input voltage changes, the reference voltage changes in linear proportion. The operational amplifier compares the two voltages and will adjust the duty cycle of the switched regulator based on any difference. The result is that the output voltage remains constant and stable, even when the input voltage fluctuates.

The LP3882EMR-1.2/NOPB has internal current limiting and thermal protection circuitry. It also includes a power-on reset circuit, which monitors the input voltage to guarantee a safe startup. The device also incorporates an internal shutdown pin, which can be used to disable the device in certain situations.
