Choose R

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 R

. If
an output voltage of 1.25 V is desired, the adjustable pin
should be connected directly to the output pin.
Thermal Characteristics
As power dissipated in the NCP690 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 NCP690 has good thermal
conductivity through the PCB, the junction temperature will
be relatively low with high power applications. The
maximum dissipation the NCP690 can handle is given by:

Since T

is not recommended to exceed 125°C (T

),
then the NCP690 can dissipate up to 1 W when the ambient
temperature (T

) is 25°C.
The power dissipated by the NCP690 can be calculated

Hints
VIN 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 NCP690, and
make traces as short as possible.
