LP3985ITLX-2.7/NOPB is a voltage regulator designed as a part of Linear’s Power Management Integrated Circuit (PMIC) family. These components provide an integrated and cost-effective solution for powering low-voltage applications, such as consumer electronics and industrial motor controls. LP3985ITLX-2.7/NOPB is a low noise voltage regulator that can be used in applications such as battery management systems, LCD power rails and sensors that require a stable and accurate output voltage.

LP3985ITLX-2.7/NOPB provides power savings for low power applications by using the I2C interface, PowerGood signal and an output sense pin. The I2C interface allows for dynamic power management, allowing user software to control and vary the output voltage. PowerGood signal is a signal that indicates when an output voltage is invalid or an over current occurs, so the user can take immediate steps to shut down the system. The output sense pin can be used to either maintain a current limit or a higher output voltage than nominal, providing flexibility for a range of applications.

LP3985ITLX-2.7/NOPB operates with a maximum input voltage of 5.5V and provides an adjustable output voltage up to 3.3V. It has a fast transient response, low output voltage ripple, and a wide operating temperature range of -40°C to +125°C. It also has an adjustable operational output current of 800 mA, which allows the regulator to be used in current or voltage outputs. This regulator is also easy to interface with as it has various options such as input/output over/under voltage, under voltage lockout, thermal shut down, output voltage and current monitoring, output voltage limits and power on/off control.

The regulator also provides a high level of protection against over-voltage surges and over-current. Overvoltage protection is provided by two external voltage sensing pins and the output voltage limit provides the user flexibility to limit the output voltage to the required level. Overcurrent protection is provided by a current limiting feature which will shut down the regulator when the current exceeds the programmed value. This feature helps protect the system from overload and provides improved reliability.

In summary, LP3985ITLX-2.7/NOPB is an advanced voltage regulator that Maintains a stable regulated voltage over voltage and current variations. It is ideal for applications such as low power consumer electronics, LCD power rails, sensors, and industrial motor controls. The regulator provides protection against over-voltage surges and over-current, with integrated I2C interface, PowerGood signal, and output sense pin. It provides adjustable output current and voltage, fast transient response, and a wide operating temperature range.
