Description

General part information

LP3990 Series

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.
