NCV8570
200 mA, Ultra Low Noise,
High PSRR, BiCMOS RF LDO
Regulator
Noise sensitive RF applications such as Power Amplifiers in satellite
radios, infotainment equipment, and precision instrumentation for
automotive applications require very clean power supplies.
The NCV8570 is 200 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 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.
Furthermore, in order to provide a small footprint for
space−conscious applications, the NCV8570 is stable with small, low
value capacitors and is available in very small DFN6 2x2.2 and
TSOP−5 packages.
