NCP629
Noise Decoupling
The NCP629 is a low noise regulator and needs no
The power dissipated by the NCP629 can be calculated
from the following equations:
external noise reduction capacitor. Unlike other low noise
regulators which require an external capacitor and have slow

(eq. 2)
startup times, the NCP629 operates without a noise
reduction capacitor, has a typical 15 m s startup delay and
achieves a 50 m V rms overall noise level between 10 Hz and
100 kHz.

(eq. 3)
Enable Operation
The enable pin will turn the regulator on or off. The
threshold limits are covered in the electrical characteristics
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
340

enable function is not to be used then the pin should be
connected to V in .
Thermal
As power in the NCP629 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

NCP629 can handle is given by:

(eq. 1)
Since T J is not recommended to exceed 125 _ C, then the
NCP629 soldered on 645 mm2, 1 oz copper area, FR4 can
dissipate up to 360 mW when the ambient temperature (T A )
is 25 _ C. See Figure 26 for R thJA versus PCB area.
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 NCP629, and
make traces as short as possible.
