The LP3871EMPX-2.5/NOPB is a fast ultra-low-dropout linear voltage regulator designed to operate with an input voltage range of 2.5 V to 7 V. It provides a specified output current of 0.8 A and features a low ground pin current, typically 6 mA at full load. The device is characterized by an ultra-low dropout voltage, which is typically 24 mV at 80 mA load current and 240 mV at 0.8 A load current, making it suitable for low voltage applications. Output voltage accuracy is ±1.5% at room temperature and ±3% across all operating conditions. The regulator includes an ERROR flag that indicates output status and a SENSE option for improved load regulation at remote loads. It also features overtemperature and overcurrent protection, ensuring reliable operation in various conditions. The LP3871EMPX-2.5/NOPB is suitable for applications such as microprocessor power supplies, bus terminators, and battery-powered devices.
