NCP703  
300 mA, Ultra-Low Quiescent  
Current, IQ 12 mA, Ultra-Low  
Noise, LDO Voltage Regulator  
Noise sensitive RF applications such as Power Amplifiers in  
satellite radios, infotainment equipment, and precision  
instrumentation require very clean power supplies. The NCP703 is  
300 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. The device doesn’t require  
any additional noise bypass capacitor to achieve ultra−low noise  
performance. In order to optimize performance for battery operated  
portable applications, the NCP703 employs dynamic Iq management  
for ultra−low quiescent current consumption at light−load conditions  
and great dynamic performance.
