ON NCP114AMX110TBG 300 ma cmos low dropout regulator Datasheet

NCP114
300 mA CMOS Low Dropout
Regulator
The NCP114 is 300 mA LDO that provides the engineer with a very
stable, accurate voltage with low noise suitable for space constrained,
noise sensitive applications. In order to optimize performance for
battery operated portable applications, the NCP114 employs the
dynamic quiescent current adjustment for very low IQ consumption at
no−load.

NCP114
APPLICATIONS INFORMATION
General
The NCP114 is a high performance 300 mA Low Dropout
Linear Regulator. This device delivers very high PSRR
(over 75 dB at 1 kHz) and excellent dynamic performance
as load/line transients. In connection with very low
quiescent current this device is very suitable for various
battery powered applications such as tablets, cellular
phones, wireless and many others. The device is fully
protected in case of output overload, output short circuit
condition and overheating, assuring a very robust design.
disable state the device consumes as low as typ. 10 nA from
the VIN.
If the EN pin voltage >0.9 V the device is guaranteed to
be enabled. The NCP114 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 300 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.
Input Capacitor Selection (CIN)
Output Current Limit
It is recommended to connect at least a 1 mF Ceramic X5R
or X7R capacitor as close as possible 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.
Output Current is internally limited within the IC to a
typical 600 mA. The NCP114 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 630 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.
Output Decoupling (COUT)
The NCP114 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 NCP114 is designed to
remain stable with minimum effective capacitance of
0.22mF 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.
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
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.
Power Dissipation
As power dissipated in the NCP114 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 NCP114 can handle
is given by:
Enable Operation
P D(MAX) +
The NCP114 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 100 W resistor. In the

nominal value. This time is dependent on various
application conditions such as VOUT(NOM), COUT and TA.
For example typical value for VOUT = 1.2 V, COUT = 1 mF,
IOUT = 1 mA and TA = 25°C is 90 ms.
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.
PCB Layout Recommendations
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 capacitors. 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 should be tied the shortest path to the GND pin.
Power Supply Rejection Ratio
The NCP114 features very good 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.
Turn−On Time
The turn−on time is defined as the time period from EN
assertion to the point in which VOUT will reach 98% of its
