Texas Instruments LP3990SDX-1-5-NOPB is a positive fixed output linear voltage regulator. This component delivers a stable 1.5V output voltage with a maximum output current of 150mA. Featuring a low dropout voltage of 0.2V at 150mA, it contributes to efficient power management. The device operates with a quiescent current of 80 µA and a maximum supply current of 120 µA. Protection features include over-temperature and short-circuit protection. The input voltage range extends up to 6V. This regulator offers a typical Power Supply Rejection Ratio (PSRR) of 55dB to 35dB across the 1kHz to 10kHz frequency range. The LP3990SDX-1-5-NOPB is supplied in a 6-WSON (3x3) package, suitable for surface mounting. Its design finds application in battery-powered devices, portable electronics, and other power-sensitive systems.
