Texas Instruments LP3873ET-1-8-NOPB is a high-performance, low-noise, positive fixed 1.8V linear voltage regulator capable of delivering up to 3A output current. Designed for robust operation, this device features over current, over temperature, and short circuit protection. Its low quiescent current of 9mA and a maximum input voltage of 7V, combined with a dropout voltage of 1.2V at 3A, make it suitable for demanding applications. The device offers excellent power supply rejection ratio (PSRR) ranging from 73dB to 57dB across a 120Hz frequency spectrum. This component is commonly utilized in telecommunications, automotive, and industrial power management systems. The LP3873ET-1-8-NOPB is supplied in a TO-220-5 package with formed leads, suitable for through-hole mounting. It operates within an ambient temperature range of -40°C to 125°C.
