Noise Decoupling
The NCV8603 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 NCV8603 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.
Enable Operation
The enable pin will turn the regulator on or off. The
threshold limits are covered in the electrical characteristics
PCB, the junction temperature will be relatively low with
high power applications. The maximum dissipation the
NCV8603 can handle is given by:
TJ(MAX) * TA
(eq. 1)
Since T J is not recommended to exceed 125 _ C (T J(MAX) ),
then the NCV8603 can dissipate up to 465 mW when the
ambient temperature (T A ) is 25 _ C and the device is
assembled on 1 oz PCB with 645 mm 2 area.
The power dissipated by the NCV8603 can be calculated
from the following equations:

table in this data sheet. The turn ? on/turn ? off transient
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
connected to V in .

As power in the NCV8603 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 NCV8603 has good thermal conductivity through the
DEVICE ORDERING INFORMATION
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 NCV8603, and
make traces as short as possible.
