NCP3985
Micropower, 150 mA
Low-Noise, High PSRR,
Ultra-Low Dropout BiCMOS
Voltage Regulator
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.
