The Texas Instruments LP3990MF-2.5/NOPB is a low-quiescent current, low-dropout linear voltage regulator suitable for portable, battery-powered systems. It provides an accurate output voltage with low noise and low quiescent current. The regulator operates from an input voltage range of 2 V to 6 V and can supply up to 150 mA of load current. Its output voltage range is from 0.8 V to 3.3 V, with a typical accuracy of 1% at room temperature.
Designed for stability with ceramic capacitors as low as 1 µF, the LP3990 features a logic-controlled enable pin for shutdown mode, reducing power consumption to virtually zero. It includes thermal-overload and short-circuit protection. The device is specified for operation over a junction temperature range of -40°C to 125°C.
Available in packages such as WSON, DSBGA, and SOT-23, this regulator is well-suited for applications requiring a stable and low-noise power supply, including cellular handsets and hand-held information appliances. Its low output noise of 150 µVRMS and high PSRR make it ideal for noise-sensitive digital applications.
