very stable, accurate voltage with ultra low noise and very high Power
Supply Rejection Ratio (PSRR) suitable for RF applications. In order
to optimize performance for battery operated portable applications,
the NCV8570 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.
