The LP3871EMP-1.8/NOPB is a fast ultra-low dropout linear regulator from Texas Instruments, designed to provide a regulated output current of 0.8 A. It operates with an input voltage range of 2.5 V to 7 V and features an ultra-low dropout voltage, typically 24 mV at 80 mA load and 240 mV at 0.8 A load. The device has a low ground pin current of approximately 6 mA at full load and a shutdown mode quiescent current of about 10 nA. Output voltage accuracy is specified at ¬±1.5% at room temperature and ¬±3% across all conditions. The LP3871 includes an error flag that indicates when the output voltage drops below 90% of its nominal value and offers a SENSE pin option to improve load regulation for remote loads. It is suitable for various applications, including microprocessor power supplies, bus terminators, and battery-powered devices, with a junction temperature range of -40¬8C to +125¬8C. The device is available in a 5-pin SOT-223 package.
