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.

Features

 Ultra Low Noise (typ. 10 mVrms @ VOUT = 1.8 V)

 Very High PSRR (typ. 82 dB @ 1 kHz)

 Excellent Line and Load Regulation

 Stable with Ceramic Output Capacitors as low as 1 mF

 Very Low Ground Current (typ. 75 mA @ IOUT = 200 mA)

 Low Sleep Mode Current (max. 1 mA)

 Active Discharge Circuit

 Current Limit and Thermal Shutdown Protection

 Output Voltage Options:



1.8 V, 2.5 V, 2.8 V, 3.0 V, 3.3 V
