NCP705

500毫安，超低静态电流，智商13 ？ A，超低噪声， LDO稳压器 500 mA, Ultra-Low Quiescent Current, IQ 13 A, 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 is a 500 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 NCP705 employs dynamic Iq management for ultra-low quiescent current consumption at light-load conditions and great dynamic performance.
