LP2989LV  
SNVS086K –MAY 2000–REVISED JULY 2015  
LP2989LV Micropower and Low-Noise, 500-mA Ultra Low-Dropout Regulator for Use With  
Ceramic Output Capacitors  
1 Features  
3 Description  
The LP2989LV is a fixed-output 500-mA precision  
LDO regulator designed for use with ceramic output  
capacitors.

2.1-V to 16-V Input Voltage Range  
Ultra-Low Dropout Voltage  
500-mA Continuous Output Current  
Output noise can be reduced to 18 μV (typical) by  
connecting an external 10-nF capacitor to the bypass  
pin.  
Very Low Output Noise With External Capacitor  
< 0.8-µA Quiescent Current When Shut Down  
Low Ground Pin Current at All Loads  
Using an optimized Vertically Integrated PNP (VIP)  
0.75% Output Voltage Accuracy (A Grade)  
High Peak Current Capability (800-mA typical)  
Overtemperature and Overcurrent Protection  
−40°C to +125°C Junction Temperature Range  
process,  
the  
LP2989LV  
delivers  
superior  
performance:  
Ground Pin Current: Typically 3 mA at 500-mA load,  
and 110 µA at 100-µA load.  
Sleep Mode: The LP2989LV draws less than 0.8-µA  
quiescent current when SHUTDOWN pin is pulled  
low.  
2 Applications  
•
•
•
•
Notebooks and Desktop PCs  
PDAs and Palmtop Computers  
Wireless Communication Pins  
SMPS Post-Regulators  
ERROR Flag: The built-in ERROR flag goes low  
when the output drops approximately 5% below  
nominal.  
Precision Output: Output voltage accuracy is 0.75%  
(A grade) and 1.25% (standard grade) at room  
temperature.  
For output voltages greater than or equal to 2 V, see  
the LP2989 (SNVS083) data sheet.

Typical Application  
*Capacitance values shown are minimum required to assure stability, but may be increased without limit. Larger  
output capacitor provides improved dynamic response. See the Output Capacitor section.  
**Shutdown must be actively terminated (see the Shutdown Input Operation section). Tie to IN (pin 4) if not use.
