Noise sensitive RF applications such as Power Amplifiers in satellite radios, infotainment equipment, and precision instrumentation require very clean power supplies. The NCP705 is 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.

Features:

Operating Input Voltage Range: 1.8 V to 5.5 V

Available in Fixed Voltage Options: 0.8 to 3.5 V Contact Factory for Other Voltage Options

Ultra-Low Quiescent Current of Typ. 13 A

Ultra-Low Noise: 12 VRMS from 100 Hz to 100 kHz

Very Low Dropout: 230 mV Typical at 500 mA

±2% Accuracy Over Load/Line/Temperature

High PSRR: 71 dB at 1 kHz

Internal Soft-Start to Limit the Turn-On Inrush Current

Thermal Shutdown and Current Limit Protections

Stable with a 1 F Ceramic Output Capacitor

Active Output Discharge for Fast Turn-Off

These are Pb-Free Devices
