3 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 0.8-
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.
For output voltages other than 0.8 V, 1.2 V, 1.35 V,
1.5 V, 1.8 V, 2.5 V, 2.8 V, or 3.3 V, please contact
the Texas Instruments sales office.
