Texas Instruments LP3874EMPX-3-3 is a linear voltage regulator designed for applications requiring a stable 3.3V output. This positive fixed output device delivers up to 800mA of current with a low dropout voltage of 0.35V at its maximum output current. The regulator features an enable pin for power sequencing and shutdown control. Protection mechanisms include over-current, over-temperature, and short-circuit protection to ensure robust operation. With a PSRR rating between 73dB and 57dB from 120Hz, it effectively filters noise from the input supply. The LP3874EMPX-3-3 is housed in an 800mA SOT-223-5 package, suitable for surface mounting. It operates across a temperature range of -40°C to 125°C, making it suitable for use in automotive, industrial, and consumer electronics.
