Update: 30 September, 2023
The LP3990 is a 150mA linear voltage regulator designed for portable, battery-powered systems providing an accurate output voltage, low noise, and low quiescent current. The LP3990 will provide a 0.8V output from the low input voltage of 2V at up to 150mA load current. When switched into shutdown mode via a logic signal at the enable pin, the power consumption is reduced to virtually zero. The LP3990 is designed to be stable with space saving ceramic capacitors as small as 0.47µF. Performance is specified for a -40˚C to 125˚C junction tem- perature range. For output voltages other than 0.8V, 1.35V, 1.5V, 1.8V, 2.5V, 2.8V, or 3.3V please contact your local NSC sales office.
