NCP700B

NCP700B LDO Regulator - Ultra Low Noise, High PSRR, BiCMOS RF 200 mA Noise sensitive RF applications such as Power Amplifiers in cell phones and precision instrumentation require very clean power supplies. The NCP700B is 200 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. In order to optimize performance for battery operated portable applications, the NCP700B employs an advanced BiCMOS process to combine the benefits of low noise and superior dynamic performance of bipolar elements with very low ground current consumption at full loads offered by CMOS. Furthermore, in order to provide a small footprint for space constrained applications, the NCP700B is stable with small, low value capacitors and is available in a very small WDFN6 1.5 mm x 1.5 mm and TSOP−5 package. Features Output Voltage Options: ♦ 1.8 V, 2.5 V, 2.8 V, 3.0 V, 3.3 V ♦ Contact Factory for Other Voltage Options Excellent Line and Load Regulation Ultra Low Noise (typ. 10 mVrms) Very High PSRR (typ 82 dB @ 1 kHz) Stable with Ceramic Output Capacitors as low as 1 mF Very Low Ground Current (typ. 70 mA @ no load) Low Disable Mode Current (max. 1 mA) Active Discharge Circuit Current Limit Protection Thermal Shutdown Protection These are Pb−Free Devices Applications Smartphones / PDAs / Palmtops / GPS Cellular Telephones (Power Amplifier) Noise Sensitive Applications...
