NCP623 D

NCP623, NCV8623
Ultra Low Noise
150 mA Low Dropout
Voltage Regulator with
ON/OFF Control
The NCP623/NCV8623 low dropout linear regulator can deliver up
to 150 mA of output current with a typical dropout voltage of 180 mV.
This low dropout feature helps to maintain a regulated output voltage
for a longer period of time as the lifetime of the battery decreases.
It is the ideal choice for noise sensitive environments like portable
applications where noise performance and space are at a premium. The
typical output noise voltage specification is 25 mVRMS. An additional
noise saving feature of this device is its ability to filter choppy signals
on the power supply by providing a typical DC ripple rejection of
−90 dB and −70 dB at 1.0 kHz.
The NCP623 is designed to work with very low ESR capacitors such
as ceramic capacitors which are common in the industry now.
Additional features such as thermal shutdown and short−circuit
protection provide for a robust system design.

NCP623, NCV8623
DEFINITIONS
Maximum Package Power Dissipation − The maximum
package power dissipation is the power dissipation level at
which the junction temperature reaches its maximum value
i.e. 125°C. The junction temperature is rising while the
difference between the input power (VCC X ICC) and the
output power (Vout X Iout) is increasing.
Depending on ambient temperature, it is possible to
calculate the maximum power dissipation, maximum load
current or maximum input voltage (see Application Hints:
Protection).
The maximum power dissipation supported by the device
is a lot increased when using appropriate application design.
Mounting pad configuration on the PCB, the board material
and also the ambient temperature are affected the rate of
temperature rise. It means that when the IC has good thermal
conductivity through PCB, the junction temperature will be
“low” even if the power dissipation is great.
The thermal resistance of the whole circuit can be
evaluated by deliberately activating the thermal shutdown
of the circuit (by increasing the output current or raising the
input voltage for example).
Then you can calculate the power dissipation by
subtracting the output power from the input power. All
variables are then well known: power dissipation, thermal
shutdown temperature (150°C for NCP623) and ambient
temperature.
Load Regulation − The change in output voltage for a
change in load current at constant chip temperature.
Dropout Voltage − The input/output differential at which
the regulator output no longer maintains regulation against
further reductions in input voltage. Measured when the
output drops 100 mV below its nominal value (which is
measured at 1.0 V differential), dropout voltage is affected
by junction temperature, load current and minimum input
supply requirements.
Output Noise Voltage − The RMS AC voltage at the
output with a constant load and no input ripple, measured
over a specified frequency range.
Maximum Power Dissipation − The maximum total
dissipation for which the regulator will operate within
specifications.
Quiescent Current − Current which is used to operate the
regulator chip and is not delivered to the load.
Line Regulation − The change in input voltage for a
change in the input voltage. The measurement is made under
conditions of low dissipation or by using pulse techniques
such that the average chip temperature is not significantly
affected.
Line Transient Response − Typical over− and
undershoot response when input voltage is excited with a
given slope.
Thermal Protection − Internal thermal shutdown
circuitry is provided to protect the integrated circuit in the
event that the maximum junction temperature is exceeded.
When activated, typically 150°C, the regulator turns off.
This feature is provided to prevent catastrophic failures from
accidental overheating.

APPLICATION HINTS
Input Decoupling − As with any regulator, it is necessary
to reduce the dynamic impedance of the supply rail that
feeds the component. A 1.0 mF capacitor either ceramic or
tantalum is recommended and should be connected close to
the NCP623 package. Higher values will correspondingly
improve the overall line transient response.
Output Decoupling − Output capacitors exhibiting ESRs
ranging from a few mW up to 3.0 W can safely be used. The
minimum decoupling value is 1.0 mF and can be augmented
to fulfill stringent load transient requirements. The regulator
works with ceramic chip capacitors as well as tantalum
devices.
Noise Performances − Unlike other LDOs, the NCP623
is a true low−noise regulator. With a 10 nF bypass capacitor,
it typically reaches 25 mVRMS overall noise between 100
Hz and 100 kHz. Spectral density graphics as well as noise
dependency versus bypass capacitor information is included
in this datasheet.
The bypass capacitor impacts the startup phase of the
NCP623 as depicted by the data−sheet curves. A typical
1.0 ms settling time is achieved with a 10 nF bypass
capacitor. However, due to its low−noise architecture, the
NCP623 can operate without bypass and thus offers a typical
20 ms startup phase. In that case, the typical output noise
stays lower than 65 mVRMS between 100 Hz − 100 kHz.
Protections − The NCP623 includes several protections
functions. The output current is internally limited to a
minimum of 175 mA while temperature shutdown occurs if
the die heats up beyond 150°C. These value lets you assess
the maximum differential voltage the device can sustain at
a given output current before its protections come into play.
The maximum dissipation the package can handle is given
by:
If TJmax is internally limited to 150°C, then the NCP623 can
dissipate up to 595 mW @ 25°C.
The power dissipated by the NCP623 can be calculated
from the following formula:
Ptot + ǀ V @ I
(I )ǁ ) ǀV * Vout ǁ @ I out
in gnd out
in
or
Vin max +
Ptot ) Vout @ I out
I
) I out
gnd
If a 150 mA output current is needed, the ground current
is extracted from the data−sheet curves: 6.5 mA @ 150 mA.
For a NCP623NW28R2 (2.8 V), the maximum input voltage
will then be 6.48 V, a rather comfortable margin.
Typical Application − The following figure portraits the
typical application for the NCP623 where both input/output
decoupling capacitors appear.

NCP623 Wake−up Improvement − In portable
applications, an immediate response to an enable signal is
vital. If noise is not a concern, the NCP623 without a bypass
capacitor settles in nearly 20 ms and typically delivers
65 mVRMS between 100 Hz and 100 kHz.
In ultra low−noise systems, the designer needs a 10 nF
bypass capacitor to decrease the noise down to 25 mVRMS
between 100 Hz and 100 kHz. With the addition of the 10 nF
capacitor, the wake−up time expands up to 1.0 ms as shown
on the data−sheet curves. If an immediate response is
wanted, Figure 3 provides a solution to charge the bypass
capacitor with the enable signal without degrading the noise
response of the NCP623.
At power−on, C4 is discharged. When the control logic
sends its wake−up signal by going high, the PNP base is
momentarily tied to ground. The PNP switch closes and
immediately charges the bypass capacitor C1 toward its
operating value. After a few ms, the PNP opens and becomes
totally transparent to the regulator.
This circuit improves the response time of the regulator
which drops from 1.0 ms down to 30 ms. The value of C4
needs to be tweaked in order to avoid any bypass capacitor
overload during the wake−up transient.
