Noise Decoupling
The NCP600 is a low noise regulator and needs no
external noise reduction capacitor. Unlike other low noise
regulators which require an external capacitor and have slow
startup times, the NCP600 operates without a noise
reduction capacitor, has a typical 15 m s start up delay and
achieves a 50 m V rms overall noise level between 10 Hz and
100 kHz.

(eq. 3)
Since T J is not recommended to exceed 125 ° C (T J(MAX) ),
then the NCP600 in a DFN6 package can dissipate up to
870 mW when the ambient temperature (T A ) is 25 ° C, and
PCB area is 640 mm 2 and larger, see Figure 33.
The power dissipated by the NCP600 can be calculated
from the following equations:
Enable Operation
The enable pin will turn the regulator on or off. The
threshold limits are covered in the electrical characteristics

voltage being supplied to the enable pin should exceed a
slew rate of 10 mV/ m s to ensure correct operation. If the
enable function is not to be used then the pin should be

Input bias current I ADJ is typically less than 150 nA.
Choose R2 arbitrarily to minimize errors due to the bias
current and to minimize noise contribution to the output
voltage. Use Equation 2 to find the required value for R1.

Thermal
As power in the NCP600 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. When
the NCP600 has good thermal conductivity through the
PCB, the junction temperature will be relatively low with
high power applications. The maximum dissipation the
NCP600 can handle is given by:
Hints
V in and GND printed circuit board traces should be as
wide as possible. When the impedance of these traces is
high, there is a chance to pick up noise or cause the regulator
to malfunction. Place external components, especially the
output capacitor, as close as possible to the NCP600, and
make traces as short as possible.
