The Texas Instruments LP3990MFX-1.8/NOPB is a low-quiescent-current, low-dropout voltage regulator designed for portable, battery-powered systems. It provides an accurate output voltage of 1.8V with a maximum load current of 150mA. The device operates from an input voltage range of 2V to 6V and features a low dropout voltage of 0.2V at 150mA.
Key features include 1% voltage accuracy at room temperature, logic-controlled enable, and thermal-overload and short-circuit protection. The LP3990 is designed to be stable with ceramic capacitors as low as 1µF, making it suitable for space-constrained applications. Its low output noise of 150µVRMS and high PSRR make it ideal for noise-sensitive digital applications.
This regulator is available in a SOT-23-5 package, suitable for surface mounting. The operating temperature range is -40°C to 125°C, ensuring reliable performance in various environments. The device also offers virtually zero quiescent current when disabled, further conserving power in battery-operated devices.
