SNVSA66A – OCTOBER 2014 – REVISED DECEMBER 2015 LP3990-Q1 150-mA Linear Voltage Regulator for Digital Applications
1 Features 3 Description The LP3990-Q1 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-Q1 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. 1 Qualified for Automotive Applications
