Introduction

AI Translation

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 ₂V 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.
