SNVS004J –MARCH 1999–REVISED APRIL 2013  
LP2987/LP2988 Micropower, 200 mA Ultra Low-Dropout Voltage Regulator with  
Programmable Power-On Reset Delay; Low Noise Version Available (LP2988)  
Check for Samples: LP2987, LP2988  
1
FEATURES  
DESCRIPTION  
The LP2987/8 are fixed-output 200 mA precision LDO  
voltage regulators with power-ON reset delay which  
can be implemented using a single external capacitor.  
2
•
Ultra Low Dropout Voltage  
•
Power-ON Reset Delay Requires Only One  
Component  
The LP2988 is specifically designed for noise-critical  
applications. A single external capacitor connected to  
the Bypass pin reduces regulator output noise.

Bypass Pin for Reduced Output Noise  
(LP2988)

•
•
•
•
•
•
•
•
Specified Continuous Output Current 200 mA  
Specified Peak Output Current > 250 mA  
SOIC-8 and VSSOP-8 Surface Mount Packages  
<2 μA Quiescent Current when Shutdown  
Low Ground Pin Current at All Loads  
Using an optimized VIP (Vertically Integrated PNP)  
process,  
these  
regulators  
deliver  
superior  
performance:  
Dropout Voltage: 180 mV @ 200 mA load, and 1  
mV @ 1 mA load (typical).  
0.5% Output Voltage Accuracy (“A” Grade)  
Wide Supply Voltage Range (16V Max)  
Overtemperature/overcurrent Protection  
−40°C to +125°C Junction Temperature Range  
Ground Pin Current: 1 mA @ 200 mA load, and 200  
μA @ 10 mA load (typical).  
Sleep Mode: The LP2987/8 draws less than 2 μA  
quiescent current when shutdown pin is held low.  
Error Flag/Reset: The error flag goes low when the  
output drops approximately 5% below nominal. This  
pin also provides a power-ON reset signal if a  
capacitor is connected to the DELAY pin.  
APPLICATIONS  
•
•
•
Cellular Phone  
Palmtop/Laptop Computer  
Camcorder, Personal Stereo, Camera  
Precision Output: Standard product versions of the  
LP2987 and LP2988 are available with output  
voltages of 5.0V, 3.8V, 3.3V, 3.2V, 3.0V, or 2.8V, with  
specified accuracy of 0.5% (“A” grade) and 1%  
(standard grade) at room temperature.
