Texas Instruments LP3855ESX-3-3 is a low-noise, low-dropout linear voltage regulator. This fixed 3.3V output device delivers up to 1.5A with a typical dropout voltage of 0.38V at 1.5A. Key features include high power supply rejection ratio (PSRR) of up to 73dB at 120Hz, an enable pin for power sequencing, and comprehensive protection circuitry including over-current, over-temperature, and short-circuit protection. Designed for surface mount applications, it is supplied in a TO-263 (DDPAK-5) package. The LP3855ESX-3-3 is well-suited for power management in automotive, industrial, and consumer electronics applications requiring stable voltage regulation.
