NCP703

300 mA, Ultra-Low Quiescent

Current, I_Q12 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.
