LP5990 Overview
The LP5990 regulator is designed to meet the requirements of portable, battery-powered systems providing an accurate output voltage, low noise and low quiescent current. The LP5990 will provide a 1.8V output from a low input voltage of 2.2V and can provide 200mA to an external load. When switched into shutdown mode via a logic signal at the enable pin, the power consumption is reduced to virtually zero.
