Texas Instruments LP3891EMRX-1-2 is a positive fixed linear voltage regulator with an output voltage of 1.2V. This component delivers 800mA of output current and features an input voltage range up to 5.5V. With a typical quiescent current of 30 µA, it is suitable for power-sensitive applications. The device includes over current, over temperature, and short circuit protection, along with under voltage lockout (UVLO). Its high power supply rejection ratio (PSRR) of 80dB to 65dB across the 120Hz to 1kHz range ensures stable operation in noisy environments. The LP3891EMRX-1-2 is available in an 8-SO PowerPad surface mount package, supplied on tape and reel. This regulator is commonly utilized in automotive, industrial, and consumer electronics power management systems.
