Ultra Low Noise, High PSSR,
BiCMOS RF LDO Regulator
Noise sensitive RF applications such as Power Amplifiers in cell
phones and precision instrumentation require very clean power supplies.
The NCP700 is 150 mA LDO that provides the engineer with a 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 NCP700 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.
Furthermore, in order to provide a small footprint for
space-conscious applications, the NCP700 is stable with small, low
value capacitors and is available in a very small DFN6 2x2.2 package.
