LP3872EMP-1.8/NOPB

The LP3872EMP-1.8/NOPB is a high-efficiency low-noise voltage regulator from Texas Instruments. This part is a low-dropout linear regulator that can provide up to 1.8A of current to a system. It operates to a voltage accuracy of ±2%. This makes it the ideal choice for use in applications where highly accurate voltage regulation is critical. It is an adjustable version of the fixed 1.8V LP3872EMP-1.8 regulator.

This part belongs in the PMIC - Voltage Regulators - Linear category. This type of device is used to regulate the voltage in circuits, by keeping the output voltage relatively stable, even when the input voltage changes. Linear regulators can be used as a simple On/Off switch or to provide a regulated output voltage. They are cost-effective, general-purpose voltage regulators which can provide good performance for most low-voltage electrical applications.

The LP3872EMP-1.8/NOPB is a low-dropout, adjustable voltage regulator. It is equipped with two control pins, EN and VSET. EN pin is an active low pin, used to enable or disable the output voltage. VSET pin is used to set the desired output voltage, using a resistive divider. The output voltage can also be trimmed for more accuracy, using a resistor or potentiometer connected across the VOUT/VSET pins.

The LP3872EMP-1.8/NOPB has a wide operating range, from 2.2V to 12V, and is designed to pass ESD tests up to 16kV (human-body model). It is designed to be thermally and transiently protected from any overcurrent conditions caused by a short circuit, with a maximum current limit of 3.3A. This device also features a frequency of 350Hz , and an EXB disconnect mode for maximum efficiency.

The LP3872EMP-1.8/NOPB is ideal for applications such as audio amplifiers, notebook chargers and battery-backed systems. It can also be used in industrial automation, robotics, automotive systems and communications, where reliability and efficiency are essential.

To sum up, the LP3872EMP-1.8/NOPB is a high-efficiency, low-noise adjustable voltage regulator, designed to provide up to 1.8A of current in systems that require highly accurate voltage regulation. It is a part of the PMIC - Voltage Regulators - Linear category, and can be used in a wide range of applications, such as audio amplifiers, notebook chargers and battery-backed systems, as well as in industrial automation and automotive systems.
