Quality Control: Learn More
The Texas Instruments LP38859SX-1-2 is a positive fixed voltage linear regulator designed for high-current applications. This device delivers a stable 1.2V output with a maximum output current of 3A. Operating from an input voltage range up to 5.5V, it features a low dropout voltage of 0.45V at 3A, contributing to efficient power management. The LP38859SX-1-2 includes robust protection features such as over current, over temperature, short circuit, and under voltage lockout (UVLO). Its high power supply rejection ratio (PSRR) of 80dB to 65dB across a frequency range of 120Hz to 1kHz makes it suitable for noise-sensitive applications. The component is supplied in a TO-263 (DDPAK-5) surface mount package and operates within an ambient temperature range of -40°C to 125°C. This regulator is commonly utilized in automotive, industrial, and consumer electronics power supply designs.
