NCP700B
200 mA, Ultra Low Noise,
High PSRR, BiCMOS RF LDO
Regulator
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.

= 25°C. Low
duty cycle pulse techniques are used during testing to maintain the junction temperature as close to ambient as possible.
5. Measured when the output voltage falls 100 mV below the nominal output voltage (nominal output voltage is the voltage at the output meas-
ured under the condition V
IN
= V
OUT
+ 0.5 V). In the case of devices having the nominal output voltage V
OUT
= 1.8 V the minimum input
to output voltage differential is given by the V
IN(MIN)
= 2.5 V.
6. The turn−on time is the time from asserting the EN to the point where output voltage reaches 98% nominal voltage level.
7. Expected to disable the device when EN pin is floating.
