APPLICATIONS INFORMATION
A typical application circuit for the NCP512 series is
shown in Figure 1, front page.
Input Decoupling (C1)
A 1.0 F capacitor either ceramic or tantalum is
recommended and should be connected close to the NCP512
package. Higher values and lower ESR will improve the
overall line transient response.
TDK capacitor: C2012X5R1C105K, or C1608X5R1A105K
Output Decoupling (C2)
The NCP512 is a stable regulator and does not require any
specific Equivalent Series Resistance (ESR) or a minimum
output current. Capacitors exhibiting ESRs ranging from a
few m up to 5.0 can thus safely be used. The minimum
decoupling value is 1.0 F and can be augmented to fulfill
stringent load transient requirements. The regulator accepts
ceramic chip capacitors as well as tantalum capacitors.
Larger values improve noise rejection and load regulation
transient response.
TDK capacitor: C2012X5R1C105K, C1608X5R1A105K,
or C3216X7R1C105K
Enable Operation
The enable pin will turn on the regulator when pulled high
and turn off the regulator when pulled low. These limits of
threshold are covered in the electrical specification section
of this data sheet. If the enable is not used then the pin should
be connected to V
in
.
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 NCP512 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 NCP512 has 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 NCP512 can dissipate up to
250 mW @ 25°C.
The power dissipated by the NCP512 can be calculated
from the following equation:

If an 80 mA output current is needed then the ground
current from the data sheet is 40 A. For an NCP512 (3.0 V),
the maximum input voltage will then be 6.12 V.
