APPLICATIONS INFORMATION

A ceramic or tantalum 0.1

mF capacitor is recommended

and should be connected close to the SCP51460 package.

Higher capacitance and lower ESR will improve the overall

line transient response.

The SCP51460 does not require any output capacitance to

be stable. With no capacitor at the output the device will have

some applications however the output capacitor could be

added. This will improve the overall transient response.

During the transients capacitors with low ESR (e.g. Ceramic

capacitors) will cause more ringing than the Tantalum or

Aluminum Capacitors.

Thermal Characteristics

As power dissipation in the SCP51460 increases, it may

become necessary to provide some thermal relief. The

maximum power dissipation supported by the device is

dependent upon board design and layout. The board material

and the ambient temperature affect the rate of junction

temperature rise for the part. The maximum power

dissipation the SCP51460 can handle is given by:

(eq. 1)

then the SCP51460 can dissipate up to 305 mW when the

The power dissipated by the SCP51460 can be calculated

from the following equations:

Hints

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 SCP51460, and

make traces as short as possible.
