DEFINITIONS
Load Regulation
Line Regulation
The change in output voltage for a change in outputcurrent at a constant temperature.
Dropout Voltage
The input/output differential at which the regulator outputno longer maintains regulation against further reductions ininput voltage. Measured when the output drops 3.0% belowits nominal. The junction temperature, load current, andminimum input supply requirements affect the dropout level.
Maximum Power Dissipation
The change in output voltage for a change in input voltage.The measurement is made under conditions of lowdissipation or by using pulse technique such that the averagechip temperature is not significantly affected.
Line Transient Response
Typical over and undershoot response when input voltageis excited with a given slope.
Thermal Protection
The maximum total dissipation for which the regulatorwill operate within its specifications.
Quiescent Current
The quiescent current is the current which flows throughthe ground when the LDO operates without a load on itsoutput: internal IC operation, bias, etc. When the LDObecomes loaded, this term is called the Ground current. It isactually the difference between the input current (measuredthrough the LDO input pin) and the output current.
Internal thermal shutdown circuitry is provided to protectthe integrated circuit in the event that the maximum junctiontemperature is exceeded. When activated at typically 160°C,the regulator turns off. This feature is provided to preventfailures from accidental overheating.
Maximum Package Power Dissipation
The maximum power package dissipation is the powerdissipation level at which the junction temperature reachesits maximum operating value, i.e. 125°C. Depending on theambient power dissipation and thus the maximum availableoutput current.

APPLICATIONS INFORMATION
A typical application circuit for the NCP662/NCV662and NCP663/NCV663 series are shown in Figure 1 andFigure 2.
Input Decoupling (C1)
Place external components, especially the outputcapacitor, as close as possible to the circuit, and make leadsas short as possible.
Thermal
A 1.0 mF capacitor, either ceramic or tantalum isrecommended and should be connected close to the devicepackage. Higher capacitance values and lower ESR willimprove the overall line transient response.
TDK capacitor: C2012X5R1C105K or C1608X5R1A105K
Output Decoupling (C2)
The NCP662/NCV662 and NCP663/NCV663 are verystable regulators and do not require any specific EquivalentSeries Resistance (ESR) or a minimum output current.Capacitors exhibiting ESRs ranging from a few mW up to10 W can safely be used. The minimum decoupling value is0.1 mF and can be augmented to fulfill stringent loadtransient requirements. The regulator accepts ceramic chipcapacitors as well as tantalum devices. Larger valuesimprove noise rejection and load regulation transientresponse.
TDK capacitor: C2012X5R1C105K, C1608X5R1A105K,or C3216X7R1C105K
Enable Operation (NCP662/NCV662 ONLY)
As power across the NCP662/NCV662 andNCP663/NCV663 increases, it might become necessary toprovide some thermal relief. The maximum powerdissipation supported by the device is dependent upon boarddesign and layout. The mounting pad configuration on thePCB, the board material, and the ambient temperature effectthe rate of temperature rise for the part. This is stating thatwhen the devices have good thermal conductivity throughthe PCB, the junction temperature will be relatively low withhigh power dissipation applications.
The maximum dissipation the package can handle isgiven by:
T*TAPD+J(max)RqJA
The enable pin will turn on the regulator when pulled highand turn off the regulator when pulled low. The thresholdlimits are covered in the electrical specification section ofthe data sheet. If the enable is not used, the pin should beconnected to Vin.
Hints
If junction temperature is not allowed above themaximum 125°C, then the NCP662/NCV662 andNCP663/NCV663 can dissipate up to 300 mW @ 25°C.The power dissipated by the NCP662/NCV662 andNCP663/NCV663 can be calculated from the followingequation:
Ptot+ƪVin*Ignd(Iout)ƫ)[Vin*Vout]*Iout
or
P)Vout*IoutVinMAX+totIgnd)Iout
Please be sure the Vin and GND lines are sufficientlywide. When the impedance of these lines is high, there is achance to pick up noise or cause the regulator tomalfunction.
If an 100 mA output current is needed then the groundcurrent from the data sheet is 2.5 mA. For theNCP662/NCV662 or NCP663/NCV663 (3.0 V), themaximum input voltage is 6.0 V.
