LP3990
150mA Linear Voltage Regulator for Digital Applications
General Description
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 0.8V 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 -40C to 125C 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.
