NCP154
Dual 300 mA, Low IQ, Low
Dropout, Dual Input Voltage
Regulator
The NCP154 is 300 mA, Dual Output Linear Voltage Regulator that
offers two independent input pins and provides a very stable and
accurate voltage with ultra low noise and very high Power Supply
Rejection Ratio (PSRR) suitable for RF applications. The device
doesn’t require any additional noise bypass capacitor to achieve ultra
low noise performance. In order to optimize performance for battery
operated portable applications, the NCP154 employs the Adaptive
Ground Current Feature for low ground current consumption during
light-load conditions.

Power supply ground. Soldered to the copper plane allows for effective heat dissipation.
OUT1
Regulated output voltage of the first channel. A small 1 mF ceramic capacitor is needed from this pin to
ground to assure stability.

OUT2
Regulated output voltage of the second channel. A small 1 mF ceramic capacitor is needed from this pin to
ground to assure stability.

EN2
Power supply ground. Soldered to the copper plane allows for effective heat dissipation.
Driving EN2 over 0.9 V turns-on OUT2. Driving EN below 0.4 V turns-off the OUT2 and activates the active
discharge.

Low Dropout Linear Regulator. This device delivers very
high PSRR (75 dB at 1 kHz) and excellent dynamic
performance as load/line transients. In connection with low
quiescent current this device is very suitable for various
battery powered applications such as tablets, cellular phones,
wireless and many others. Each output is fully protected in
case of output overload, output short circuit condition and
overheating, assuring a very robust design. The NCP154
device is housed in XDFN−8 1.6 mm x 1.2 mm package
which is useful for space constrains application.
The both 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.
Output Current Limit
Output Current is internally limited within the IC to a
typical 400 mA. The NCP154 will source this amount of
current measured with a voltage drops on the 90% of the
nominal V

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. or 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

short circuit protection will work properly over whole
temperature range and also input voltage range. There is no
limitation for the short circuit duration. This protection
works separately for each channel. Short circuit on the one
channel do not influence second channel which will work
according to specification.
Thermal Shutdown
When the die temperature exceeds the Thermal Shutdown
threshold (T − 160°C typical), Thermal Shutdown event

remain in this state until the die temperature decreases below
Output Decoupling (COUT
)
The NCP154 requires an output capacitor for each output
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 NCP154 is
designed to remain stable with minimum effective
capacitance of 0.33 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.

This protection is not intended to be used as a substitute for
proper heat sinking. The long duration of the short circuit

maximum value of ESR should be less than 3 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.
As power dissipated in the NCP154 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 NCP154 can handle
is given by:
Enable Operation
The NCP154 uses the dedicated EN pin for each output
channel. This feature allows driving outputs separately.
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 V
is pulled to GND through a 50 W resistor. In the disable state
the device consumes as low as typ. 10 nA from the V .

PCB Layout Recommendations
To obtain good transient performance and good regulation
characteristics place input and output 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 NCP154 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 C
capacitor and proper PCB layout.
