Texas Instruments LP3891EMR-1-8 is a low-dropout linear voltage regulator designed for applications requiring stable 1.8V output. This device delivers up to 800mA of continuous output current with a typical quiescent current of 30µA. The regulator features an input voltage range up to 5.5V and a dropout voltage of 0.43V at maximum load. Included protection mechanisms encompass over current, over temperature, short circuit, and under voltage lockout (UVLO). The LP3891EMR-1-8 offers excellent Power Supply Rejection Ratio (PSRR) performance, ranging from 80dB to 65dB across the 120Hz to 1kHz frequency spectrum. It is supplied in an 8-SO PowerPad package suitable for surface mounting and operates within a temperature range of -40°C to 125°C. This component is utilized in various industries including automotive, industrial automation, and consumer electronics.
