Voltage Regulator
www.onsemi.com
The NCV8705 is a low noise, low power consumption and low
dropout Linear Voltage Regulator. With its excellent noise and PSRR
specifications, the device is ideal for use in products utilizing RF
receivers, imaging sensors, audio processors or any component
requiring an extremely clean power supply. The NCV8705 uses an
innovative Adaptive Ground Current circuit to ensure ultra low
ground current during light load conditions.

Dropout Linear Regulator. This device delivers excellent
noise and dynamic performance. Thanks to its adaptive
ground current feature the device consumes only 13 mA of
quiescent current at no*load condition. The regulator
features ultra*low noise of 12 mVRMS, PSRR of 71 dB at
1 kHz and very good load/line transient performance. Such
excellent dynamic parameters and small package size make
the device an ideal choice for powering the precision analog
and noise sensitive circuitry in portable applications. The
LDO achieves this ultra low noise level output without the
need for a noise bypass capacitor. A logic EN input provides
ON/OFF control of the output voltage. When the EN is low
the device consumes as low as typ. 10 nA from the IN pin.
The device is fully protected in case of output overload,
output short circuit condition and overheating, assuring a
very robust design.

DC BIAS (V)
Figure 64. Capacitance Change vs. DC Bias
No−load Operation
The regulator remains stable and regulates the output
voltage properly within the 2% tolerance limits even with
no external load applied to the output.
Input Capacitor Selection (CIN)
It is recommended to connect a minimum of 1 mF Ceramic
X5R or X7R capacitor close to the IN pin of the device. 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 min. /max. 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. Larger input capacitor
may be necessary if fast and large load transients are
encountered in the application.
Adjustable Operation
The output voltage range can be set from 0.8 V to
5.5 V−V by resistor divider network. Use Equations 1
DO
and 2 to calculate appropriate values of resistors and output
voltage. Typical current to ADJ pin is 1 nA. For output
voltage 0.8 V ADJ pin can be tied directly to Vout pin.

The NCV8705 requires an output capacitor connected as
close as possible to the output pin of the regulator. The
minimal capacitor value is 1 mF and X7R or X5R dielectric
due to its low capacitance variations over the specified
temperature range. The NCV8705 is designed to remain
stable with minimum effective capacitance of 1 mF to
account for changes with temperature, DC bias and package
size. Especially for small package size capacitors such as
0402 the effective capacitance drops rapidly with the
applied DC bias. Refer to the Figure 64, for the capacitance
vs. package size and DC bias voltage dependence.
The resistor divider should be designed carefully to
achieve the best performance. Recommended current
through divider is 10 mA and more. Too high values of
resistors (MW) cause increasing noise and longer start−up
time. The suggested values of the resistors are in Table 5. To
improve dynamic performance capacitor C1 should be at
least 1 nF. Recommended range of capacity is between
10 nF and 100 nF. Higher value of capacitor C1 increasing
start−up time.
There is no requirement for the minimum value of

maximum value of ESR should be less than 900 mΩ. Larger
output capacitors and lower ESR could improve the load
transient response or high frequency PSRR as shown in
typical characteristics. It is not recommended to use
tantalum capacitors on theoutput due to their large ESR. The
equivalent series resistance of tantalum capacitors is also
strongly dependent on the temperature, increasing at low
temperature. The tantalum capacitors are generally more
costly than ceramic capacitors.

Enable Operation
The NCV8705 uses the EN pin to enable/disable its device
and to deactivate/activate the active discharge function.
If the EN pin voltage >0.9 V the device is guaranteed to
be enabled. The NCV8705 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 110 nA which assures that the device is
turned−off when the EN pin is not connected. Build in 2 mV

oscillations that can occur due to noise.

SDU
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 NCV8705 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
ambient temperature affect the rate of junction temperature
rise for the part.
In the case where the EN function isn’t required the EN
should be tied directly to IN.

Output Noise
The IC is designed for ultra−low noise output voltage
without external noise filter capacitor (C ). Figures 3 − 6
nr
shows NCV8705 noise performance. Generally the noise
performance in the indicated frequency range improves with
increasing output current.
Load Regulation
The NCV8705 features very good load regulation of
maximum 2 mV in 0 mA to 500 mA range. In order to
achieve this very good load regulation a special attention to
PCB design is necessary. The trace resistance from the OUT
pin to the point of load can easily approach 100 mW which
will cause 50 mV voltage drop at full load current,
deteriorating the excellent load regulation.
Turn−On Time
The turn−on time is defined as the time period from EN
