Texas Instruments LP3990MF-1-5-NOPB is a fixed output voltage linear regulator designed for applications requiring stable power delivery. This positive voltage regulator provides a 1.5V output with a maximum output current of 150mA. It features a low quiescent current of 80µA and a low dropout voltage of 0.2V at 150mA, making it suitable for battery-powered devices. Protection features include over-temperature and short-circuit protection. The device operates with an input voltage range up to 6V and offers a Power Supply Rejection Ratio (PSRR) of 55dB to 35dB over the 1kHz to 10kHz frequency range. The LP3990MF-1-5-NOPB is supplied in a SOT-23-5 package, facilitating surface mount assembly, and is available on tape and reel. This component finds application in portable electronics, battery management systems, and general-purpose voltage regulation.
