Texas Instruments LP3891ET-1-2-NOPB is an 800mA positive fixed linear voltage regulator. This device features an 800mA output current capability and a low quiescent current of 30 µA. The voltage dropout at maximum output current is 0.4V. The regulator offers robust protection features including over current, over temperature, short circuit, and under voltage lockout (UVLO). With an input voltage range up to 5.5V and a fixed output of 1.2V, it is suitable for applications requiring stable voltage regulation. The PSRR performance ranges from 80dB to 65dB across a frequency range of 120Hz to 1kHz. This component is designed for through-hole mounting in a TO-220-5 package and operates within an ambient temperature range of -40°C to 125°C. It is commonly utilized in industrial and automotive power supply designs.
