NCV8163
250 mA, Ultra-Low Noise
and High PSRR LDO
Regulator for RF and
Analog Circuits
The NCV8163 is a next generation of high PSRR, ultra−low noise
LDO capable of supplying 250 mA output current. Designed to meet
the requirements of RF and sensitive analog circuits, the NCV8163
device provides ultra−low noise, high PSRR and low quiescent
current. The device also offer excellent load/line transients. The
NCV8163 is designed to work with a 1 mF input and a 1 mF output
ceramic capacitor. It is available in XDFN4 0.65P, 1 mm x 1 mm and
TSOP−5 packages.

Description
Input voltage supply pin
Regulated output voltage. The output should be bypassed with small 1 mF ceramic capacitor.
Chip enable: Applying VEN < 0.4 V disables the regulator, Pulling VEN > 1.2 V enables the LDO.
Exposed Pad. Exposed pad can be tied to ground plane for better power dissipation.

Product parametric performance is indicated in the Electrical Characteristics for the listed test conditions, unless otherwise noted. Product
performance may not be indicated by the Electrical Characteristics if operated under different conditions.
4. Performance guaranteed over the indicated operating temperature range by design and/or characterization. Production tested at TA = 25°C.
Low duty cycle pulse techniques are used during the testing to maintain the junction temperature as close to ambient as possible.
5. Dropout voltage is characterized when VOUT falls 100 mV below VOUT(NOM).
6. Guaranteed by design.

NCV8163
APPLICATIONS INFORMATION
General
transient response or high frequency PSRR. It is not
recommended to use tantalum capacitors on the output due
to their large ESR. The equivalent series resistance of
tantalum capacitors is also strongly dependent on the
temperature, increasing at low temperature.
The NCV8163 is an ultra−low noise 250 mA low dropout
regulator designed to meet the requirements of RF
applications and high performance analog circuits. The
NCV8163 device provides very high PSRR and excellent
dynamic response. In connection with low quiescent current
this device is well suitable for battery powered application
such as cell phones, tablets and other. The NCV8163 is fully
protected in case of current overload, output short circuit and
overheating.
Enable Operation
Input capacitor connected as close as possible is necessary
for ensure device stability. The X7R or X5R capacitor
should be used for reliable performance over temperature
range. The value of the input capacitor should be 1 mF or
greater to ensure the best dynamic performance. This
capacitor will provide a low impedance path for unwanted
AC signals or noise modulated onto constant input voltage.
There is no requirement for the ESR of the input capacitor
but it is recommended to use ceramic capacitors for their low
ESR and ESL. A good input capacitor will limit the
influence of input trace inductance and source resistance
during sudden load current changes.
The NCV8163 uses the EN pin to enable/disable its device
and to deactivate/activate the active discharge function.
If the EN pin voltage is <0.4 V the device is guaranteed to
be disabled. The pass transistor is turned−off so that there is
virtually no current flow between the IN and OUT. The
active discharge transistor is active so that the output voltage
VOUT is pulled to GND through a 280 W resistor. In the
disable state the device consumes as low as typ. 10 nA from
the VIN.
If the EN pin voltage >1.2 V the device is guaranteed to
be enabled. The NCV8163 regulates the output voltage and
the active discharge transistor is turned−off.
The EN pin has internal pull−down current source with
typ. value of 200 nA which assures that the device is
turned−off when the EN pin is not connected. In the case
where the EN function isn’t required the EN should be tied
directly to IN.
Output Decoupling (COUT)
Output Current Limit
Input Capacitor Selection (CIN)
The NCV8163 requires an output capacitor connected as
close as possible to the output pin of the regulator. The
recommended capacitor value is 1 mF and X7R or X5R
dielectric due to its low capacitance variations over the
specified temperature range. The NCV8163 is designed to
remain stable with minimum effective capacitance of 0.7 mF
to account for changes with temperature, DC bias and
package size. Especially for small package size capacitors
such as 0201 the effective capacitance drops rapidly with the
applied DC bias. Please refer Figure 47.
Output Current is internally limited within the IC to a
typical 700 mA. The NCV8163 will source this amount of
current measured with a voltage drops on the 90% of the
nominal VOUT. If the Output Voltage is directly shorted to
ground (VOUT = 0 V), the short circuit protection will limit
the output current to 690 mA (typ). The current limit and
short circuit protection will work properly over whole
temperature range and also input voltage range. There is no
limitation for the short circuit duration.
Thermal Shutdown
When the die temperature exceeds the Thermal Shutdown
threshold (TSD − 160°C typical), Thermal Shutdown event
is detected and the device is disabled. The IC will remain in
this state until the die temperature decreases below the
Thermal Shutdown Reset threshold (TSDU − 140°C typical).
Once the IC temperature falls below the 140°C the LDO is
enabled again. The thermal shutdown feature provides the
protection from a catastrophic device failure due to
accidental overheating. This protection is not intended to be
used as a substitute for proper heat sinking.
Power Dissipation
As power dissipated in the NCV8163 increases, it might
become necessary to provide some thermal relief. The
maximum power dissipation supported by the device is
dependent upon board design and layout. Mounting pad
configuration on the PCB, the board material, and the
Figure 47. Capacity vs DC Bias Voltage
There is no requirement for the minimum value of
Equivalent Series Resistance (ESR) for the COUT but the
maximum value of ESR should be less than 2 W. Larger
output capacitors and lower ESR could improve the load

Reverse Current
Turn−On Time
The PMOS pass transistor has an inherent body diode
which will be forward biased in the case that VOUT > VIN.
Due to this fact in cases, where the extended reverse current
condition can be anticipated the device may require
additional external protection.
The turn−on time is defined as the time period from EN
assertion to the point in which VOUT will reach 98% of its
nominal value. This time is dependent on various
application conditions such as VOUT(NOM), COUT, TA.
Power Supply Rejection Ratio
To obtain good transient performance and good regulation
characteristics place CIN and COUT capacitors close to the
device pins and make the PCB traces wide. In order to
minimize the solution size, use 0402 or 0201 capacitors with
appropriate capacity. Larger copper area connected to the
pins will also improve the device thermal resistance. The
actual power dissipation can be calculated from the equation
above (Equation 2). Expose pad can be tied to the GND pin
for improvement power dissipation and lower device
temperature.
PCB Layout Recommendations
The NCV8163 features very high Power Supply
Rejection ratio. If desired the PSRR at higher frequencies in
the range 100 kHz – 10 MHz can be tuned by the selection
of COUT capacitor and proper PCB layout.
