Поставка оригинальных LP3982ILDX-3.3/NOPB, PMIC - Линейные стабилизаторы напряжения, от Texas Instruments

The LP3982ILDX-3.3/NOPB is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments. It is designed to provide a stable output voltage of 3.3V with a maximum output current of 200mA. This device is particularly useful in applications where space is limited and efficiency is critical, such as in portable electronics, battery-powered devices, and other low-power applications.

Key Features:

1. Output Voltage: The LP3982 provides a fixed output voltage of 3.3V, making it suitable for powering various digital circuits and microcontrollers that require this specific voltage level.

2. Low Dropout Voltage: The LDO features a low dropout voltage of approximately 300mV at full load, which allows it to maintain regulation even when the input voltage is close to the output voltage. This is particularly beneficial in battery-operated devices where maximizing battery life is essential.

3. Quiescent Current: The device has a low quiescent current, typically around 30µA, which helps to extend battery life in portable applications by minimizing power consumption when the device is in a standby mode.

4. Thermal Protection: The LP3982 includes built-in thermal shutdown protection, which prevents the device from overheating and ensures reliable operation under varying load conditions.

5. Output Capacitor: It is stable with a wide range of output capacitors, including ceramic capacitors, which are often preferred in compact designs due to their small size and low equivalent series resistance (ESR).

6. Package Type: The LP3982ILDX-3.3/NOPB is available in a small, space-saving package (such as the SOT-23), making it ideal for applications where PCB real estate is at a premium.

7. Lead-Free: The "NOPB" designation indicates that the part is lead-free, complying with environmental regulations such as RoHS, making it suitable for use in environmentally sensitive applications.
