The Texas Instruments LP3871EMP-5.0/NOPB is a fast, ultra-low-dropout linear regulator designed for input voltages from 2.5V to 7V. It provides a stable 5V output at up to 800mA of DC current.
Key electrical specifications include an ultra-low dropout voltage, typically 240mV at 0.8A load, and a load regulation of 0.04%. The device features a low quiescent current of 6mA at 0.8A load and only 10nA in shutdown mode. It also includes an ERROR flag to indicate output status and overtemperature/overcurrent protection.
This regulator is developed on a CMOS process, allowing for low quiescent current operation independent of the output load. Its fast response to load steps makes it suitable for low-voltage microprocessor applications. The LP3871EMP-5.0/NOPB is available in a SOT-223-5 package, requiring surface mount.
Applications include microprocessor power supplies, bus terminators, DSP power supplies, and battery chargers. The device operates within a junction temperature range of -40°C to 125°C.
