LP3991 300-mA LDO for Digital Applications  
1 Features  
3 Description  
Operating from a minimum input voltage of 1.65 V,  
1
Input Voltage From 1.65 V to 4 V  
the LP3991 LDO has been designed to provide fixed  
stable output voltages for load currents up to 300 mA.  
This device is suitable where accurate low voltages  
are required from low input voltage sources and is  
therefore suitable for post regulation of switched  
mode regulators. In such applications, significant  
improvements in performance and EMI can be  
realized, with little reduction in overall efficiency. The  
LP3991 provides fixed outputs as low as 1.2 V from a  
wide input range from 1.65 V to 4 V Using the enable  
(EN) pin, the device may be controlled to provide a  
shutdown state, in which negligible supply current is  
drawn.  
Output Voltage From 0.8 V to 3 V  
1% Accuracy at Room Temperature  
125-mV Dropout at 300-mA Load  
50-µA Quiescent Current at 1-mA Load  
Inrush Current Controlled to 600 mA  
PSRR 65 dB at 1 kHz  
100-µs Start-Up Time for 1.5-V VOUT  
Stable With Ceramic Capacitors as Small as 0402  
Thermal-Overload and Short-Circuit Protection  
2 Applications  
The LP3991 is designed to be stable with space-  
saving ceramic capacitors as small as 0402 case  
size.  
Post DC-DC Regulator  
Battery Operated Devices  
Hand-Held Information Appliances  
Performance is specified for a –40°C to +125°C  
junction temperature range. For output voltage  
options, contact your local Texas Instruments sales  
office.
