LP2989LV  
Micropower 500 mA Low Noise Low Dropout Regulator  
<
for Applications with Output Voltages 2V  
Designed for Use with Very Low ESR Output Capacitors  
General Description  
Features  
n Ultra low dropout voltage  
The LP2989LV is a 500 mA fixed-output voltage regulator  
designed to provide high performance and low noise in  
n Guaranteed 500 mA continuous output current  
n Very low output noise with external capacitor  
n SO-8, Mini SO-8, 8 Lead LLP surface mount packages  
<
applications requiring output voltages 2V.  
Output noise can be reduced to 18µV (typical) by connecting  
an external 10 nF capacitor to the bypass pin.  
<
n
0.8 µA quiescent current when shutdown  
Using an optimized VIP (Vertically Integrated PNP) pro-  
n Low ground pin current at all loads  
cess, the LP2989LV delivers superior performance:  
n 0.75% output voltage accuracy (“A” grade)  
n High peak current capability (800 mA typical)  
n Wide supply voltage range (16V max)  
n Overtemperature/overcurrent protection  
n −40˚C to +125˚C junction temperature range  
@
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 quies-  
cent current when shutdown pin is pulled low.  
Error Flag: The built-in error flag goes low when the output  
drops approximately 5% below nominal.  
Applications  
Precision Output: Guaranteed output voltage accuracy is  
0.75% (“A” grade) and 1.25% (standard grade) at room  
temperature.  
n Notebook/Desktop PC  
n PDA/Palmtop Computer  
n Wireless Communication Terminals  
n SMPS Post-Regulator  
For output voltages 2V, see LP2989 datasheet.
