1% Voltage Accuracy at Room Temperature  
Stable with Ceramic Capacitor  
Cellular Handsets  
Hand-Held Information Appliances  
Logic Controlled Enable  
5 Description  
No Noise Bypass Capacitor Required  
Thermal-Overload and Short-Circuit Protection  
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  
150-mA load current. When switched into shutdown  
mode via a logic signal at the enable pin, the power  
consumption is reduced to virtually zero.  
2 Key Specifications  
Input Voltage Range, 2.0 to 6.0 V  
Output Voltage Range, 0.8 to 3.3 V  
Output Current, 150 mA  
Output Stable - Capacitors, 1.0 µF  
Virtually Zero IQ (Disabled), <10 nA  
Very Low IQ (Enabled), 43 µA  
Low Output Noise, 150 µVRMS  
PSRR, 55 dB at 1 kHz  
The LP3990 is designed to be stable with space  
saving ceramic capacitors as small as 1.0 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.  
Fast Start-up, 105 µs  
3 Package  
All available in Lead-Free option:  
4-bump DSBGA, 1 mm x 1.3 mm  
6-pin WQFN (SOT-23 Footprint)  
SOT-23  
For other package options contact your Texas Instruments sales office.
