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 NCP552 series andNCP553 series is shown in Figure 1 and Figure 2, front page.

Input Decoupling (C1)

A 1.0 mF capacitor either ceramic or tantalum isrecommended and should be connected close to the package.Higher values and lower ESR will improve the overall linetransient response. If large line or load transients are notexpected, then it is possible to operate the regulator withoutthe use of a capacitor.

TDK capacitor: C2012X5R1C105K, or C1608X5R1A105K

Output Decoupling (C2)

chance to pick up noise or cause the regulator tomalfunction.

Set external components, especially the output capacitor,as close as possible to the circuit, and make leads as short aspossible.

Thermal

The NCP552 and NCP553 are very stable regulators anddo not require any specific Equivalent Series Resistance(ESR) or a minimum output current. If load transients are notto be expected, then it is possible for the regulator to operatewith no output capacitor. Otherwise, capacitors exhibitingESRs ranging from a few mW up to 10 W can thus safely beused. The minimum decoupling value is 0.1 mF and can beaugmented to fulfill stringent load transient requirements.The regulator accepts ceramic chip capacitors as well astantalum devices. Larger values improve noise rejection andload regulation transient response.

TDK capacitor: C2012X5R1C105K, C1608X5R1A105K,or C3216X7R1C105K

Enable Operation (NCP552 ONLY)

As power across the NCP552 and NCP553 increases, itmight become 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 devices have goodthermal 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

If junction temperature is not allowed above themaximum 125°C, then the NCP552 and NCP553 candissipate up to 250 mW @ 25°C.

The power dissipated by the NCP552 and NCP553 can becalculated from the following equation:

Ptot+[Vin*Ignd(Iout)])[Vin*Vout]*Iout

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.

If an 80 mA output current is needed then the groundcurrent from the data sheet is 2.8 mA. For an NCP552 orNCP553 (3.0 V), the maximum input voltage will then be6.12 V.
