LP2988AIM-3.0/NOPB

The LP2988AIM-3.0/NOPB is a precise, low voltage, low power, linear voltage regulator. It is a three-terminal device designed to regulate the output electrical characteristics of negative voltages with a dropout voltage of typically 0.4V. This device is suitable for applications such as portable device battery management, Li-ion battery charger, cellular handsets, and other low-power battery backed systems where low power dissipation and thermal protection are important.

The LP2988AIM-3.0/NOPB offers enhanced line and load regulation which extends from 0.4V to 1V. It has low power consumption, and it also offers very low dropout voltage for low power inputs. It has very low power dissipation and thermal protection, which makes it ideal for battery management in portable devices.

The LP2988AIM-3.0/NOPB\'s application field includes: battery management, Li-ion battery charger, cellular handsets, etc. Its working principle includes the following three points:

Input voltage and current regulation - The LP2988AIM-3.0/NOPB uses a low dropout voltage and current regulation to maintain an input voltage as close as possible to the reference voltage. When the voltage is expected to drop, the regulator cuts off input current to prevent uncontrolled operation.

Output voltage and current regulation - The LP2988AIM-3.0/NOPB provides a very precise output voltage and current regulation, with a field-programmable output voltage range of 0.4V to 1V and a highly-accurate output current range. With the help of its adjustable output current, it is able to maintain the output voltage and current within a very wide range.

Thermal protection - The LP2988AIM-3.0/NOPB has a low power dissipation and thermal protection circuit in order to protect the device from external heat sources. When the temperature of the device rises above a certain level, the thermal protection circuit shuts down the device and prevents it from over-heating.

In conclusion, the LP2988AIM-3.0/NOPB is a low voltage, low power linear voltage regulator that can provide enhanced power management, low power consumption and very low dropout regulation. It is ideally suited for applications such as battery management in portable devices, Li-ion battery chargers and cellular handsets.
