LP3982ILD-2.5/NOPB

The LP3982ILD-2.5/NOPB is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments. It is designed to provide a stable output voltage with high accuracy and low noise, making it suitable for a variety of applications, including portable devices, battery-powered equipment, and other sensitive electronic circuits.

Key Features:

1. Output Voltage: The LP3982 is fixed at 2.5V, which is ideal for powering low-voltage digital circuits and components.

2. Low Dropout Voltage: The device features a low dropout voltage, typically around 300 mV at full load, allowing it to maintain regulation even when the input voltage is close to the output voltage. This is particularly beneficial in battery-operated applications where maximizing battery life is crucial.

3. High Output Current: The LP3982 can deliver up to 200 mA of output current, making it suitable for a range of applications that require moderate power levels.

4. Low Quiescent Current: The regulator has a low quiescent current, which helps to extend battery life in portable applications by minimizing power consumption when the device is in a standby mode.

5. Power Supply Rejection Ratio (PSRR): The LP3982 offers excellent PSRR, which helps to filter out noise from the input supply, ensuring a clean and stable output voltage.

6. Thermal Protection: The device includes thermal shutdown protection, which prevents damage due to overheating by shutting down the regulator if the junction temperature exceeds a certain threshold.

7. Compact Package: The LP3982 is available in a small, surface-mount package (such as the LLP or VQFN), which is advantageous for space-constrained designs.

8. Operating Temperature Range: The device operates over a wide temperature range, typically from -40°C to +125°C, making it suitable for industrial and automotive applications.

9. Application Versatility: It is commonly used in applications such as RF power amplifiers, portable devices, and other consumer electronics where a stable voltage supply is critical.

Pin Configuration:

The LP3982 typically features a simple pin configuration that includes:

• Input Pin (Vin): The pin where the input voltage is applied.
• Ground Pin (GND): The common ground connection.
• Output Pin (Vout): The pin that provides the regulated output voltage.

Conclusion:

The LP3982ILD-2.5/NOPB from Texas Instruments is a reliable and efficient LDO voltage regulator that combines low dropout voltage, low quiescent current, and high output current capability. Its robust features make it an excellent choice for a wide range of electronic applications, particularly where space and power efficiency are critical.
