The Texas Instruments LP3990MFX-3.3 is a low-quiescent-current, low-dropout voltage regulator designed for portable, battery-powered systems. It provides an accurate output voltage with low noise and low quiescent current. The regulator is stable with ceramic capacitors as low as 1 µF and features a logic-controlled enable pin for shutdown mode, reducing power consumption to virtually zero.
Key electrical specifications include an input voltage range of 2V to 6V and an output voltage range of 0.8V to 3.3V, with a maximum output current of 150 mA. It boasts 1% voltage accuracy at room temperature, a typical dropout voltage of 0.2V at 150mA, and low output noise of 150 µVRMS. The device also includes thermal-overload and short-circuit protection.
This regulator is supplied in a space-saving SOT-23-5 package, suitable for surface mounting. Its operating temperature range is -40°C to 85°C. The LP3990 is ideal for applications requiring a stable, low-noise power supply, such as cellular handsets and hand-held information appliances.
