Low Noise, Low Dropout
Regulator
The NCP717 is 300 mA LDO that provides the engineer with a very
stable, accurate voltage with very low noise suitable for space
constrained, noise sensitive applications. In order to optimize
performance for battery operated portable applications, the NCP717
MARKING

Pin Name
Description
1
OUT
Regulated output voltage pin. A small ceramic capacitor with minimum value of 1
m
F is needed from this
pin to ground to assure stability.
2
3
GND
EN
Power supply ground.
Driving EN over 0.9 V turns on the regulator. Driving EN below 0.4 V puts the regulator into shutdown
mode.
4
−
IN
Input pin. A small capacitor is needed from this pin to ground to assure stability.
EPAD
Exposed pad should be connected directly to the GND pin. Soldered to a large ground copper plane allows
for effective heat removal.

NCP717
APPLICATIONS INFORMATION
The NCP717 is a high performance, small package size,
to GND through a 1.2 k
W
resistor (A version) or 120
W
300 mA LDO voltage regulator. This device delivers very
good noise and dynamic performance. Thanks to its adaptive
ground current feature the device consumes only 25
m
A of
quiescent current at no−load condition. The regulator
features very−low noise of 22
m
VRMS, PSRR of typ. 70 dB
at 1 kHz and very good load/line transient response. The
device is an ideal choice for space constrained portable
applications.
(C version). In the disable state the device consumes as low
as typ. 10 nA from the V
. If the EN pin voltage > 0.9 V the
IN
device is guaranteed to be enabled. The NCP717 regulates
the output voltage and the active discharge transistor is
turned−off. The EN pin has an internal pull−down current
source with typ. value of 180 nA which assures that the
device is turned−off when the EN pin is not connected. A
build in 56 mV of hysteresis and deglitch time in the EN block
prevents from periodic on/off oscillations that can occur due
to noise on EN line. In the case that the EN function isn’t
required the EN pin should be tied directly to IN.
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.
Reverse Current
The PMOS pass transistor has an inherent body diode
which will be forward biased in the case that V
> V
.

Due to this fact in cases where the extended reverse current
condition is anticipated the device may require additional
external protection.
Input Capacitor Selection (C
IN
)
It is recommended to connect a minimum of 1
μ
F Ceramic
X5R or X7R capacitor close to the IN pin of the device.
Larger input capacitors may be necessary if fast and large
load transients are encountered in the application. 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.
Output Current Limit
Output Current is internally limited within the IC to a
typical 379 mA. The NCP717 will source this amount of
current measured with the output voltage 100 mV lower
than the nominal V
shorted to ground (V

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 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.

but the maximum value of ESR should be less than 700 m
Ω
.
Larger output capacitors could be used to improve the load
transient response or high frequency PSRR characteristics.
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
tantalum capacitors are generally more costly than ceramic
capacitors.
Power Dissipation
No−load Operation
As power dissipated in the NCP717 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. The maximum power dissipation the
NCP717 can handle is given by:
The regulator remains stable and regulates the output
voltage properly within the
2% tolerance limits even with
no external load applied to the output.
Enable Operation
The NCP717 uses the EN pin to enable/disable its output
and to control 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

Load Regulation
The NCP717 features very good load regulation of typical
3.6 mV in the 0 mA to 300 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
100 kHz − 10 MHz it can be tuned by the selection of C
capacitor and proper PCB layout.
