NCV8570B
200 mA, Ultra Low Noise,
High PSRR, LDO, Linear
Voltage Regulator
The NCV8570B is a 200 mA Low Dropout, Linear Voltage
Regulator with ultra low noise characteristics. It’s low noise combined
with high Power Supply Rejection Ratio (PSRR) make it especially
suited for use in RF, audio or imaging applications. The device is
manufactured in an advanced BiCMOS process to provide a powerful
combination of low noise and excellent dynamic performance but with
very low ground current consumption at full loads.
The NCV8570B is stable with small, low value capacitors allowing
designers to minimise the total PCB space occupied by the solution.
The device is packaged in a small 2x2.2mm DFN6 package as well as
in a TSOP-5 package.
