The LP3981ILD-3.0/NOPB is a low-dropout (LDO) linear voltage regulator designed and manufactured by Texas Instruments, a leader in semiconductor solutions. This regulator is specifically engineered to provide a stable and reliable power supply for sensitive electronics, with a fixed output voltage of 3.0 volts.

Key Features

• Low Dropout Voltage: The device maintains regulation with a minimal difference between the input and output voltages, enhancing efficiency in operation and allowing for lower input voltage sources.
• High Accuracy: With an output voltage accuracy of ±1%, the LP3981ILD-3.0/NOPB ensures precise voltage delivery for critical applications.
• Low Quiescent Current: The regulator is designed for battery-powered devices, featuring a low quiescent current that extends battery life by minimizing standby power consumption.
• Thermal Shutdown Protection: The built-in thermal shutdown feature protects the device from damage due to overheating, enhancing the longevity and reliability of both the regulator and the application it powers.
• Current Limit Protection: This safety feature prevents damage to the regulator and the load by limiting the output current during fault conditions.

Applications

The LP3981ILD-3.0/NOPB is versatile and can be used in a variety of applications, including but not limited to:

• Mobile phones and PDAs
• Digital cameras and portable media players
• Wireless LAN and Bluetooth® devices
• GPS receivers

Package and Quality

Encased in a small 8-lead LLP package, the LP3981ILD-3.0/NOPB is designed for space-constrained applications. It is also available in a "Green" MSL (Moisture Sensitivity Level) compliant package, which is free from lead (Pb), halogens, and antimony trioxide, making it an environmentally conscious choice. The NOPB in the part number indicates that this product is RoHS compliant.

As with all Texas Instruments products, the LP3981ILD-3.0/NOPB is manufactured to the highest quality standards, ensuring reliability and performance for critical applications.
