The LP3990 regulator is designed to meet the requirements of portable, battery-powered systems providing an accurate output voltage, low-noise, and low-quiescent current. The LP3990 will provide a 0.8-V output from the low input voltage of 2 V at up to a 150-mA load current. When switched into shutdown mode via a logic signal at the enable pin (EN), the power consumption is reduced to virtually zero.The LP3990 is designed to be stable with space-saving ceramic capacitors with values as low as 1 μF.Performance is specified for a –40°C to 125°C junction temperature range. For output voltages other than 0.8 V, 1.2 V, 1.35 V, 1.5 V, 1.8 V, 2.5 V, 2.8 V, or 3.3 V, please contact the Texas Instruments sales office.

The LP3990 is designed for portable RF and wireless applications with demanding performance and space requirements. The LP3990 performance is optimized for battery-powered systems to deliver ultra low noise and low quiescent current. The LP3990 also works with low-ESR ceramic capacitors, reducing the amount of board space necessary for power applications, critical in hand-held wireless devices. The LP3990 consumes less than 0.01μA in shutdown mode and has fast turn-on time less than 50μs. The other features include ultra low dropout voltage, high output accuracy, current limiting protection, and high ripple rejection ratio. It is available in the 1mm×1mm X2SON packages.
