SNVS251J MAY 2004REVISED SEPTEMBER 2014  
LP3990 150-mA Linear Voltage Regulator for Digital Applications  
1 Features  
3 Description  
The LP3990 regulator is designed to meet the  
1
1% Voltage Accuracy at Room Temperature  
Stable with Ceramic Capacitor  
Logic Controlled Enable  
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.  
No Noise Bypass Capacitor Required  
Thermal-Overload and Short-Circuit Protection  
Input Voltage Range, 2 V to 6 V  
Output Voltage Range, 0.8 V to 3.3 V  
Output Current, 150 mA  
The LP3990 is designed to be stable with space-  
saving ceramic capacitors with values as low as 1 µF.  
Output Stable - Capacitors, 1 µF  
Virtually Zero IQ (Disabled), < 10 nA  
Very Low IQ (Enabled), 43 µA  
Low Output Noise, 150 µVRMS  
PSRR, 55 dB at 1 kHz  
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.
