SNVS086J MAY 2000REVISED APRIL 2013  
LP2989LV Micropower 500 mA Low Noise Low Dropout Regulator for Applications with  
Output Voltages < 2V  
Designed for Use with Very Low ESR Output Capacitors  
Check for Samples: LP2989LV  
1
FEATURES  
DESCRIPTION  
The LP2989LV is a 500 mA fixed-output voltage  
regulator designed to provide high performance and  
low noise in applications requiring output voltages <  
2V.  
2
Ultra Low Dropout Voltage  
Ensured 500 mA Continuous Output Current  
Very Low Output Noise with External  
Capacitor  
Output noise can be reduced to 18µV (typical) by  
connecting an external 10 nF capacitor to the bypass  
pin.  
SOIC-8, VSSOP, 8 Lead WSON Surface Mount  
Packages  
<0.8 μA Quiescent Current when Shut Down  
Low Ground Pin Current at All Loads  
Using an optimized VIP (Vertically Integrated PNP)  
process,  
the  
LP2989LV  
delivers  
superior  
performance:  
0.75% Output Voltage Accuracy (“A” Grade)  
High Peak Current Capability (800 mA Typical)  
Wide Supply Voltage Range (16V Max)  
Ground Pin Current: Typically 3 mA @ 500 mA load,  
and 110 µA @ 100 µA load.  
Sleep Mode: The LP2989LV draws less than 0.8 μA  
quiescent current when shutdown pin is pulled low.  
Overtemperature/Overcurrent Protection  
40°C to +125°C Junction Temperature Range  
Error Flag: The built-in error flag goes low when the  
output drops approximately 5% below nominal.  
APPLICATIONS  
Notebook/Desktop PC  
Precision Output: Ensured output voltage accuracy is  
0.75% (“A” grade) and 1.25% (standard grade) at  
room temperature.  
PDA/Palmtop Computer  
Wireless Communication Terminals  
SMPS Post-Regulator  
For output voltages 2V, see LP2989 data sheet.
