NCP59800 Datasheet, PDF (1/6 Pages) ON Semiconductor – Low Noise, RF LDO Voltage Regulator

NCP59800
1 A Low Noise, RF LDO
Voltage Regulator
The NCP59800 is a family of 1 A low−dropout linear regulators
(LDOs) offering high power−supply ripple rejection (PSRR) and
ultra−low output noise. This series of LDOs uses an advanced
BiCMOS process to achieve very good electrical performance. It is an
ideal choice for noise sensitive Analog RF Front−Ends used in
Telecom Equipment. The NCP59800 is available in the 3 mm x 3 mm
DFN8 package.
Features
• Operating Input Voltage Range: 2.2 V to 6.0 V
• Output Voltage Range:
♦ Fixed V_OUT: 0.8 to 5 V (0.1 V steps)
♦ Adjustable V_OUT: 0.8 V to 5 V
• Quiescent Current typ. 60 mA
• Low Dropout: 200 mV typ. at 1 A, V_OUT = 2.5 V
• ±2.5% V_OUT Accuracy across Load/Line/Temperature
• Stable with Small 4.7 mF Ceramic Capacitors
• Very−Low Noise: Typically 15 mV_RMS from 100 Hz to 100 kHz
• Over−Current and Thermal Shutdown Protection
• Available in 3 x 3 mm DFN8 Package
Typical Applications
• Telecom Infrastructure
• Audio
• High−Speed I/F (PLL/VCO)
