APPLICATIONS INFORMATION
A typical application circuit for the NCP553 series is
shown in Figure 1, front page.
Input Decoupling (C1)
A 1.0 mF capacitor either ceramic or tantalum is
recommended and should be connected close to the package.
Higher values and lower ESR will improve the overall line
transient response. If large line or load transients are not
expected, then it is possible to operate the regulator without
the use of a capacitor.
TDK capacitor: C2012X5R1C105K, or C1608X5R1A105K
Output Decoupling (C2)
The NCP553 are very stable regulators and do not require
any specific Equivalent Series Resistance (ESR) or a
minimum output current. If load transients are not to be
expected, then it is possible for the regulator to operate with
no output capacitor. Otherwise, capacitors exhibiting ESRs
ranging from a few mW up to 10 W can thus safely be used.
The minimum decoupling value is 0.1 mF and can be
augmented to fulfill stringent load transient requirements.
The regulator accepts ceramic chip capacitors as well as
tantalum devices. Larger values improve noise rejection and
load regulation transient response.
TDK capacitor: C2012X5R1C105K, C1608X5R1A105K,
or C3216X7R1C105K
Hints
Please be sure the Vin and GND lines are sufficiently
wide. When the impedance of these lines is high, there is a
chance to pick up noise or cause the regulator to
malfunction.
Set external components, especially the output capacitor,
as close as possible to the circuit, and make leads as short as
possible.
Thermal
As power across the NCP553 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 also the ambient
temperature effect the rate of temperature rise for the part.
This is stating that when the devices have good thermal
conductivity through the PCB, the junction temperature will
be relatively low with high power dissipation applications.
The maximum dissipation the package can handle is
given by:

If junction temperature is not allowed above the
maximum 125°C, then the NCP553 can dissipate up to
250 mW @ 25°C.
The power dissipated by the NCP553 can be calculated
from the following equation:

If an 80 mA output current is needed then the ground
current from the data sheet is 2.8 mA. For an NCP553
(3.0 V), the maximum input voltage will then be 6.12 V.
