200 mA Low Noise RF Low Dropout Linear Voltage 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 Low Dropout (LDO) Linear Voltage Regulator is a 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 a very small DFN6 2x2.2 and TSOP-5 packages. NOTE FOR NEW DESIGNS THE NCV8570B IS RECOMMENDED IN PLACE NCV8570.
