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. 150°C. Depending on theambient power dissipation and thus the maximum availableoutput current.

APPLICATIONS INFORMATION
A typical application circuit for the NCP612/NCV612 isshown in Figure 1, front page.
Input Decoupling (C1)
Set external components, especially the output capacitor,as close as possible to the circuit, and make leads as short aspossible.
Thermal
A 1.0 mF capacitor either ceramic or tantalum isrecommended and should be connected close to theNCP612/NCV612 package. Higher values and lower ESRwill improve the overall line transient response.
TDK capacitor: C2012X5R1C105K, or C1608X5R1A105K
Output Decoupling (C2)
The NCP612/NCV612 is a stable regulator and does notrequire any specific Equivalent Series Resistance (ESR) ora minimum output current. Capacitors exhibiting ESRsranging from a few mW up to 5.0 W can thus safely be used.The minimum decoupling value is 1.0 mF and can beaugmented to fulfill stringent load transient requirements.The regulator accepts ceramic chip capacitors as well astantalum capacitors. Larger values improve noise rejectionand load regulation transient response.
TDK capacitor: C2012X5R1C105K, C1608X5R1A105K,or C3216X7R1C105K
Enable Operation
As power across the NCP612/NCV612 increases, it mightbecome necessary to provide some thermal relief. Themaximum power dissipation supported by the device isdependent upon board design and layout. Mounting padconfiguration on the PCB, the board material and also theambient temperature effect the rate of temperature rise forthe part. This is stating that when the NCP612/NCV612 hasgood thermal conductivity through the PCB, the junctiontemperature will be relatively low with high powerdissipation 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. These limits ofthreshold are covered in the electrical specification sectionof this data sheet. If the enable is not used then the pin shouldbe connected to Vin.
Hints
If junction temperature is not allowed above themaximum 125°C, then the NCP612/NCV612 can dissipateup to 330 mW @ 25°C.
The power dissipated by the NCP612/NCV612 can becalculated from the following equation:
Ptot+[Vin*Ignd(Iout)])[Vin*Vout]*Iout
or
P)Vout*Iout
VinMAX+tot
Ignd)Iout
Please be sure the Vin and Gnd lines are sufficiently wide.When the impedance of these lines is high, there is a chanceto pick up noise or cause the regulator to malfunction.
If an 100 mA output current is needed then the groundcurrent from the data sheet is 40 mA. For anNCP612/NCV612 (3.0 V), the maximum input voltage willthen be 6.0 V (Limited by maximum input voltage).
