MC33263
Ultra Low Noise
150 mA Low Dropout
Voltage Regulator with
ON/OFF Control
http://onsemi.com
Housed in a SOT23–L package, the MC33263 delivers up to
150 mA where it exhibits a typical 180 mV dropout. With an
incredible noise level of 25 mVRMS (over 100 Hz to 100 kHz, with a
10 nF bypass capacitor), the MC33263 represents the ideal choice for
sensitive circuits, especially in portable applications where noise
performance and space are premium. The MC33263 also excels in
response time and reacts in less than 25 ms when receiving an OFF to
ON signal (with no bypass capacitor).
Thanks to a novel concept, the MC33263 accepts output capacitors
without any restrictions regarding their Equivalent Series Resistance
(ESR) thus offering an obvious versatility for immediate implementation.
With a typical DC ripple rejection better than –90 dB (–70 dB @
1.0 kHz), it naturally shields the downstream electronics against
choppy power lines.

DEFINITIONS
Load Regulation – The change in output voltage for a
This feature is provided to prevent catastrophic failures from
accidental overheating.
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
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.
difference between the input power (V X I ) and the
CC
CC
output power (V X I ) is increasing.
out
out
Depending on ambient temperature, it is possible to
calculate the maximum power dissipation, maximum load
current or maximum input voltage (see Application Hints:
Protection).
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.
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 I has good thermal
C
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).
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.
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 MC33263) and ambient
temperature.

MC33263
APPLICATION HINTS
Input Decoupling – As with any regulator, it is necessary
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 MC33263NW28R2 (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 MC33263 where both
input/output decoupling capacitors appear.
to reduce the dynamic impedance of the supply rail that
feeds the component. A 1 mF capacitor either ceramic or
tantalum is recommended and should be connected close to
the MC33263 package. Higher values will correspondingly
improve the overall line transient response.
Output Decoupling – Thanks to a novel concept, the
MC33263 is a stable component and does not require any
Equivalent Series Resistance (ESR) neither a minimum
output current. Capacitors exhibiting ESRs ranging from a
few mW up to 3 W can thus safely be used. The minimum
decoupling value is 1 mF and can be augmented to fulfill
stringent load transient requirements. The regulator accepts
ceramic chip capacitors as well as tantalum devices.
Noise Performances – Unlike other LDOs, the MC33263
is a true low–noise regulator. With a 10 nF bypass capacitor,
it typically reaches the incredible level of 25 mVRMS overall
noise between 100 Hz and 100 kHz. To give maximum
insight on noise specifications, ON Semiconductor includes
spectral density graphics as well as noise dependency versus
bypass capacitor.

The bypass capacitor impacts the start–up phase of the
MC33263 as depicted by the data–sheet curves. A typical
1 ms settling time is achieved with a 10 nF bypass capacitor.
However, thanks to its low–noise architecture, the
MC33263 can operate without bypass and thus offers a
typical 20 ms start–up phase. In that case, the typical output
noise stays lower than 65 mVRMS between 100 Hz –
100 kHz.

Recommended Capacitor Values
Protections – The MC33263 hosts several protections,
conferring natural ruggedness and reliability to the products
implementing the component. 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.

As for any low noise designs, particular care has to be
MC33263 Wake–up Improvement – In portable
applications, an immediate response to an enable signal is
vital. If noise is not of concern, the MC33263 without a
bypass capacitor settles in nearly 20 ms and typically delivers
65 mVRMS between 100 Hz and 100 kHz.
taken when tackling Printed Circuit Board (PCB) layout.
The following figure gives an example of a layout where
stray inductances/capacitances are minimized.
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 adjunction of the
10 nF capacitor, the wake–up time expands up to 1 ms as
shown on the data–sheet curves. If an immediate response
is wanted, following figure’s circuit gives a solution to
charge the bypass capacitor with the enable signal without
degrading the noise response of the MC33263.
At power–on, C4 is discharged. When the control logic
sends its wake–up signal by going to a high level, the PNP
base is momentarily tight 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 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.

Package Placement – QFN packages can be placed using
standard pick and place equipment with an accuracy of
"0.05 mm. Component pick and place systems are
composed of a vision system that recognizes and positions
the component and a mechanical system which physically
performs the pick and place operation. Two commonly used
types of vision systems are: (1) a vision system that locates
a package silhouette and (2) a vision system that locates
individual bumps on the interconnect pattern. The latter type
renders more accurate place but tends to be more expensive
and time consuming. Both methods are acceptable since the
parts align due to a self–centering feature of the QFN solder
joint during solder re–flow.

Re–flow and Cleaning – The QFN may be assembled
using standard IR/IR convection SMT re–flow processes
without any special considerations. As with other packages,
the thermal profile for specific board locations must be
determined. Nitrogen purge is recommended during solder
for no–clean fluxes. The QFN is qualified for up to three
re–flow cycles at 235°C peak (J–STD–020). The actual
