Texas Instruments LP3871EMPX-3-3 is a linear voltage regulator designed for high-performance applications. This positive fixed output device provides a stable 3.3V with a maximum output current of 800mA. Featuring an ultra-low dropout voltage of 0.35V at 800mA, it minimizes power dissipation. The regulator includes robust protection features such as over current, over temperature, and short circuit protection. With an input voltage range up to 7V and a quiescent current of 5mA, it is suitable for power-sensitive designs. The device offers an enable pin for power sequencing and control. Its performance is further characterized by a Power Supply Rejection Ratio (PSRR) ranging from 73dB to 57dB across a frequency range of 120Hz. The LP3871EMPX-3-3 is supplied in a SOT-223-5 (TO-261-5) surface-mount package, typically on tape and reel. This component finds application in diverse sectors including telecommunications, industrial control, and consumer electronics.
