AdjustableOperation The adjustabledeviceistestedand specifiedwiththe ADJ pintiedto the OUT pinforan outputvoltageof 1.21V. Specificationsforoutputvoltagesgreaterthan1.21V are proportionaltotheratioofthedesiredoutput voltageto1.21V: VOUT /1.21V. For example,loadregulationforan outputcurrentchange of1 mA to1.5A is –3 mV (typ)atVOUT = 1.21V.AtVOUT = 5 V,loadregulationis: Output Capacitanceand TransientResponse The TL1963A-xx regulatorsare designedtobe stablewitha wide range ofoutputcapacitors.The ESR ofthe outputcapacitoraffectsstability,most notablywithsmallcapacitors.A minimum outputcapacitorof10 μF with an ESR of3 Ω orlessisrecommended topreventoscillations.Largervaluesofoutputcapacitancecan decrease thepeak deviationsand provideimprovedtransientresponseforlargerloadcurrentchanges.Bypass capacitors, used to decoupleindividualcomponents powered by the TL1963A-xx,increasethe effectiveoutputcapacitor value. Extraconsiderationmust be giventotheuse ofceramiccapacitors.Ceramic capacitorsaremanufacturedwitha varietyof dielectrics,each withdifferentbehaviorover temperatureand appliedvoltage.The most common dielectricsused are Z5U, Y5V, X5R and X7R. The Z5U and Y5V dielectricsare good forprovidinghigh capacitancesina smallpackage,butexhibitstrongvoltageand temperaturecoefficients.When used witha 5-V regulator,a 10-μF Y5V capacitorcan exhibitan effectivevalueas low as 1 μF to 2 μF over the operating temperaturerange.The X5R and X7R dielectricsresultinmore stablecharacteristicsand aremore suitablefor use as the outputcapacitor.The X7R type has betterstabilityacross temperature,whilethe X5R is less expensiveand isavailableinhighervalues. Voltageand temperaturecoefficientsare not the onlysourcesof problems.Some ceramiccapacitorshave a piezoelectricresponse.A piezoelectricdevicegeneratesvoltageacrossitsterminalsdue tomechanicalstress, similartotheway a piezoelectricaccelerometerormicrophoneworks.For a ceramiccapacitorthestresscan be inducedby vibrationsinthesystemorthermaltransients. Overload Recovery Likemany IC power regulators,the TL1963A-xx has safeoperatingarea protection.The safearea protection decreasesthe currentlimitas input-to-outputvoltageincreasesand keeps the power transistorinsidea safe operatingregionforallvaluesof input-to-outputvoltage.The protectionisdesignedto providesome output currentatallvaluesofinput-to-outputvoltageup tothedevicebreakdown. When power isfirstturnedon,as theinputvoltagerises,theoutputfollowstheinput,allowingtheregulatorto startup intovery heavy loads.During startup, as the inputvoltageis rising,the input-to-outputvoltage differentialissmall,allowingtheregulatortosupplylargeoutputcurrents.With a highinputvoltage,a problem can occurwhereinremovalofan outputshortdoes notallowtheoutputvoltagetorecover.Otherregulatorsalso exhibitthisphenomenon, so itisnotuniquetotheTL1963A-xx.

The problem occurswitha heavy outputloadwhen the inputvoltageishighand the outputvoltageislow. Common situationsareimmediatelyaftertheremovalofa shortcircuitorwhen theshutdown pinispulledhigh aftertheinputvoltagehas alreadybeen turnedon.The loadlineforsuch a loadmay intersecttheoutputcurrent curveat two points.Ifthishappens,thereare two stableoutputoperatingpointsforthe regulator.With this doubleintersection,theinputpower supplymay need tobe cycleddown tozeroand broughtup againtomake theoutputrecover. Output VoltageNoise The TL1963A-xx regulatorshave been designedtoprovidelow outputvoltagenoiseoverthe10-Hz to100-kHz bandwidthwhileoperatingatfullload.Outputvoltagenoiseistypically40 nV/√Hz overthisfrequencybandwidth forthe TL1963A (adjustableversion).For higheroutputvoltages(generatedby usinga resistordivider),the outputvoltagenoiseisgainedup accordingly.ThisresultsinRMS noiseoverthe10-Hz to100-kHz bandwidthof 14 μVRMS fortheTL1963A, increasingto38 μVRMS fortheTL1963A-3.3. Highervaluesofoutputvoltagenoisemay be measured when careisnotexercisedwithregardstocircuitlayout and testing.Crosstalkfrom nearby tracescan induce unwanted noise onto the outputof the TL1963A-xx. Power-supplyripplerejectionmust also be considered;the TL1963A-xx regulatorsdo not have unlimited power-supplyrejectionand pass a smallportionoftheinputnoisethroughtotheoutput. Thermal Considerations The power handlingcapabilityofthedeviceislimitedby themaximum ratedjunctiontemperature(125°C).The power dissipatedby thedeviceismade up oftwo components: 1. Outputcurrentmultipliedby theinput/outputvoltagedifferential:IOUT (VIN – VOUT ) 2. GND pincurrentmultipliedby theinputvoltage:IGND VIN. The GND pin currentcan be found using the GND Pin Currentgraphs in TypicalCharacteristics. Power dissipationisequaltothesum ofthetwo components listedabove. The TL1963A-xx seriesregulatorshave internalthermallimitingdesignedtoprotectthedeviceduringoverload conditions.For continuousnormal conditions,the maximum junctiontemperatureratingof 125°C must not be exceeded.Itisimportantto givecarefulconsiderationto allsourcesof thermalresistancefrom junctionto ambient.Additionalheatsourcesmounted nearbymust alsobe considered.

CalculatingJunctionTemperature Example:Givenan outputvoltageof3.3V,an inputvoltagerangeof4 V to6 V,an outputcurrentrangeof0 mA to500 mA, and a maximum ambienttemperatureof50°C, what isthemaximum junctiontemperature? The power dissipatedby thedeviceisequalto: IOUT(MAX) (VIN(MAX) – VOUT )+ IGND (VIN(MAX)) where, IOUT(MAX) = 500 mA VIN(MAX) = 6 V IGND at(IOUT = 500 mA, VIN = 6 V) = 10 mA So, P = 500 mA (6V – 3.3V) + 10 mA (6V) = 1.41W Using a KTT package,thethermalresistanceisintherange of23°C/W to33°C/W, dependingon thecopper area.So thejunctiontemperatureriseabove ambientisapproximatelyequalto: The maximum junctiontemperatureisthenbe equaltothemaximum junction-temperatureriseabove ambient plusthemaximum ambienttemperatureor: TJMAX = 50°C + 39.5°C = 89.5°C ProtectionFeatures The TL1963A-xx regulatorsincorporateseveral protectionfeaturesthat make them ideal for use in battery-poweredcircuits.Inadditiontothenormalprotectionfeaturesassociatedwithmonolithicregulators,such as currentlimitingand thermallimiting,thedevicesareprotectedagainstreverseinputvoltages,reverseoutput voltagesand reversevoltagesfromoutputtoinput.

The inputofthedevicewithstandsreversevoltagesof20 V. Currentflowintothedeviceislimitedtolessthan 1 mA (typicallylessthan100 μA),and no negativevoltageappearsattheoutput.The deviceprotectsbothitself and theload.Thisprovidesprotectionagainstbatteriesthatcan be pluggedinbackward.

Insituationswhere theADJ pinisconnectedtoa resistordividerthatwould pulltheADJ pinabove its7-V clamp voltageiftheoutputispulledhigh,theADJ pininputcurrentmust be limitedtolessthan5 mA. For example,a resistordividerisused toprovidea regulated1.5-Voutputfromthe1.21-Vreferencewhen theoutputisforcedto 20 V. The topresistoroftheresistordividermust be chosen tolimitthecurrentintotheADJ pintolessthan 5 mA when the ADJ pin isat 7 V.
