MARKING  
DIAGRAM  
The NCP3985 is 150 mA LDO that provides the engineer with a  
very stable, accurate voltage with low noise and high Power Supply  
Rejection Ratio (PSRR) suitable for sensitive applications. In order to  
optimize performance for battery operated portable applications, the  
NCP3985 employs an advanced BiCMOS process to combine the  
benefits of low noise and superior dynamic performance of bipolar  
elements with very low ground current consumption at full loads  
offered by CMOS.
