Texas Instruments LP3874EMPX-1-8 is a low-dropout linear voltage regulator offering a fixed 1.8V output with an 800mA maximum output current from a positive voltage input up to 7V. This device features a 0.35V dropout voltage at its maximum load. The regulator includes an enable pin for power sequencing and protection against over-current, over-temperature, and short circuits. Its high power supply rejection ratio (PSRR) ranges from 73dB to 57dB across a 120Hz frequency range, making it suitable for noise-sensitive applications. The LP3874EMPX-1-8 is packaged in a SOT-223-5 (TO-261-5) surface-mount configuration, supplied on tape and reel. Typical applications include power supplies for consumer electronics, automotive systems, and telecommunications equipment where stable voltage regulation is critical. Quiescent current is 9mA, with a supply current of 15mA maximum. Operating temperature range is -40°C to 125°C.
