Texas Instruments LP3891ES-1-2 is an 800mA positive fixed linear voltage regulator. This component provides a stable 1.2V output and features an enable pin for control. Its low quiescent current of 30 µA and robust protection features, including over current, over temperature, short circuit, and under voltage lockout (UVLO), make it suitable for demanding applications. The device offers excellent power supply rejection ratio (PSRR) ranging from 80dB to 65dB across the 120Hz to 1kHz frequency spectrum. Packaged in a TO-263-6, D2PAK surface-mount format, it operates within a temperature range of -40°C to 125°C. The maximum input voltage is 5.5V, with a dropout voltage of 0.4V at 800mA. This regulator finds application in sectors such as automotive, industrial, and consumer electronics.
