Texas Instruments LP3891EMR-1-2 is a positive fixed output voltage linear regulator with an 800mA output current capability. This device operates from an input voltage range up to 5.5V, providing a stable 1.2V output. Key features include low quiescent current of 30 µA and a low dropout voltage of 0.43V at 800mA. The regulator incorporates comprehensive protection features such as over current, over temperature, short circuit, and under voltage lockout (UVLO). Its power supply rejection ratio (PSRR) ranges from 80dB to 65dB across a 120Hz to 1kHz frequency band. The LP3891EMR-1-2 is supplied in an 8-SO PowerPad surface mount package, suitable for applications in automotive, industrial, and communications sectors. It includes an enable pin for control functionality.
